Andy Walker Urges Celtic to Replace Goalkeeping Duo in Glasgow 2026

• Former Celtic forward Andy Walker has called on the club to sign an undisputed number one goalkeeper ahead of Sam Johnstone and Viljami Sinisalo.
• Manager Martin O’Neill has rotated both goalkeepers throughout the current season, maintaining that direct competition between them is beneficial.
• Walker believes Johnstone is currently performing as a third-choice option and lacks the standard required to start ahead of Sinisalo.
• Pundits and observers argue that frequent chopping and changing between goalkeepers creates instability within the Celtic defensive unit.
• Walker insists Celtic should re-enter the transfer market during the January window to secure a definitive solution to their goalkeeping dilemma.

Glasgow (Glasgow Express) October 28, 2026 – Celtic manager Martin O’Neill is facing growing calls to end his ongoing goalkeeping rotation policy, with former Celtic forward and football analyst Andy Walker urging the club to move on from both Sam Johnstone and Viljami Sinisalo by securing a definitive first-choice goalkeeper. The goalkeeping situation at Celtic Park has become a central point of debate this season, as O’Neill and his coaching staff have regularly alternated between Johnstone and Sinisalo without establishing a clear primary starter. While O’Neill has publicly defended the strategy, stating that healthy competition drives performance, critics argue that the lack of consistency in goal is undermining team stability.

Why Is the Celtic Goalkeeping Rotation Causing Concern?

The debate surrounding Celtic’s selection between the posts has intensified following a series of tactical shifts by the management team. Both Johnstone, who joined the club with considerable experience, and Sinisalo, the younger Finnish international, have been handed extended runs in the starting lineup this season. However, neither goalkeeper has managed to secure the position permanently, leading to persistent squad rotation.

In commentary regarding the situation, Walker expressed strong reservations about the current arrangement. According to Walker, the ongoing rotation indicates a lack of decisive clarity from the managerial team. Walker argued that a club of Celtic’s stature requires a clear and unchallenged starting goalkeeper to maintain defensive coherence across domestic and European competitions.

Walker further voiced criticism regarding the performance levels of Johnstone, suggesting that his output has fallen below expectation. Walker noted that Johnstone currently resembles a third-choice option rather than a senior starter and asserted that Sinisalo possesses greater relative quality between the two. Despite evaluating Sinisalo above Johnstone, Walker concluded that neither player currently offers the level of authority necessary to lead Celtic’s backline over a full campaign.

How Has Martin O’Neill Responded to the Goalkeeping Debate?

Despite the mounting external scrutiny, O’Neill has firmly rejected suggestions that alternating his goalkeepers presents a problem for the squad. The Celtic manager has consistently maintained that having two capable goalkeepers vying for a single position creates a positive competitive environment that prevents complacency.

O’Neill’s approach relies on evaluating form and match-specific requirements before deciding who starts. During recent media interactions, the manager highlighted that both goalkeepers understand the parameters of the competition and are expected to perform whenever called upon. O’Neill has emphasized that modern squad management often requires flexibility across multiple competitions, including domestic league fixtures, cup ties, and European matches.

However, football analysts continue to question whether this philosophy aligns with traditional defensive stability. Pundits point out that central defenders generally benefit from building a consistent understanding with a regular goalkeeper, particularly regarding communication during set pieces and organization of the defensive line.

What Are Andy Walker’s Recommended Transfer Solutions for Celtic?

To address the perceived issue, Walker has advised the Celtic board and recruitment team to take decisive action in the upcoming transfer windows. Rather than continuing with the current pair, Walker advocates for entering the transfer market to sign a top-tier, undisputed number one goalkeeper.

Walker stated that Celtic should actively seek an immediate recruit during the January transfer window to resolve the issue before the final stretch of the season. Walker argued that relying on two competing goalkeepers who lack the full confidence of the coaching staff could prove costly in high-stakes matches. By securing an established, high-calibre goalkeeper, Walker believes Celtic would immediately solidify their defense and provide clear leadership from the back.

The recommendation places focus on Celtic’s recruitment strategy, which has previously balanced experienced domestic acquisitions with prospective international talent. Whether the club’s hierarchy chooses to sanction significant expenditure on a new goalkeeper in January remains subject to ongoing assessment by the management team.

Background of the Particular Development

Celtic’s current goalkeeping situation stems from a period of transition within the squad’s positional hierarchy. Following changes in the squad roster ahead of the current campaign, the club brought in both Sam Johnstone and Viljami Sinisalo to strengthen their options between the posts. Johnstone arrived with extensive English league experience, having featured for clubs in the Premier League and Championship, while Sinisalo was acquired as a promising international prospect with strong physical attributes and growth potential.

Initially, it was anticipated that one of the two arrivals would quickly assert authority and claim the starting spot on a permanent basis. However, early-season performances and minor fitness interruptions led to alternating selections. Rather than appointing a permanent primary goalkeeper, the management opted to prolong the selection trial across multiple competitions.

This approach has generated extensive discussion among former players, media commentators, and supporters. While some view the dual-option system as practical depth against injuries and fixture congestion, others see it as an indicator that neither goalkeeper has fully convinced the management of their ability to maintain long-term consistency.

Prediction: How This Development Can Affect Celtic, the Squad, and Their Supporters

The unresolved goalkeeping hierarchy at Celtic Park carries direct implications for the club’s sporting trajectory, squad dynamics, and overall supporter sentiment over the remainder of the season.

Impact on Defensive Performance and Squad Dynamics

If O’Neill maintains his rotation policy without signing an undisputed primary goalkeeper, the primary risk involves a potential breakdown in defensive organization. Defenders rely heavily on predictable communication, positioning cues, and physical presence from their goalkeeper. Frequent changes in goal can lead to hesitation during high-pressure defensive scenarios, particularly during opposition crosses and set pieces. Conversely, if Celtic act on Walker’s advice and secure a recognized first-choice goalkeeper in the January transfer window, it could instantly stabilize the backline, boost defensive confidence, and allow Johnstone and Sinisalo to seek clarity regarding their respective roles.

Impact on the Players Involved

For Johnstone and Sinisalo, prolonged competition without clear positional hierarchy can create psychological strain. While healthy rivalry can drive short-term performance, continuous media debate and public scrutiny may eventually erode player confidence. Should Celtic recruit a new number one, one or both current goalkeepers may evaluate their future options away from Parkhead in search of guaranteed playing time elsewhere.

Impact on the Supporters and Season Objectives

For the Celtic fanbase and broader audience, the goalkeeping situation remains a focal point of anxiety during close title races and continental fixtures. Supporters traditionally favor a settled starting lineup, particularly in core central positions. A definitive decision by O’Neill—whether through backing one current goalkeeper unequivocally or entering the transfer market—will likely be viewed by fans as a critical metric of the club’s ambition and strategic clarity for the season ahead.
