Angus Gunn is facing questions over his place in the Scotland goal after a difficult night at Hampden Park saw the hosts slump to a 3-0 defeat by Switzerland in Sebastien Pocognoli's first match in charge on home soil.
The contest was effectively decided early on when Jack Hendry was sent off in the 11th minute for denying Dan Ndoye a clear goalscoring opportunity. Referee Nenad Minakovic initially pointed to the penalty spot, but a VAR review downgraded the decision to a free-kick just outside the box. Scotland appeared to have escaped serious punishment, only for Ricardo Rodriguez to fire the resulting set-piece past Gunn to put Switzerland ahead.
Switzerland doubled their advantage when Nico Elvedi turned in a cross from Ndoye, before Zeki Amdouni added a third with a powerful strike that beat Gunn at his near post. The San Jose Earthquakes goalkeeper did produce a couple of important saves to deny Ndoye either side of half-time, preventing the scoreline from ballooning further, but the three goals conceded have reignited debate about Scotland's options between the posts.
Former Scotland defender Andy Halliday, speaking as a pundit on Sportsound, was critical of Gunn's positioning for the opener, describing the free-kick as being struck with only moderate pace and at a height the goalkeeper should have dealt with. He argued that Gunn was also culpable for the third goal, suggesting that previous Scotland number ones would likely have kept out Amdouni's effort.
Former international forward James McFadden echoed similar sentiments regarding the third goal, saying that despite the power of Amdouni's shot, it was one Gunn should have saved.
Halliday went further, questioning whether there is currently a genuine challenger pushing Gunn for the starting jersey, given that several of Scotland's other goalkeeping options are not featuring regularly for their clubs. He acknowledged that Gunn remains the deserved incumbent but suggested there is less confidence in him compared to previous long-serving Scotland goalkeepers such as Craig Gordon, Allan McGregor, David Marshall, Jim Leighton and Andy Goram.
Gunn, 30, started all three of Scotland's matches at the World Cup, ahead of Liam Kelly and the now-retired Craig Gordon, who remarkably remained part of the squad at the finals at the age of 43. Gordon's continued involvement at that stage underlined the lack of depth Scotland have had competing for the goalkeeping position in recent years. For this Nations League campaign, Falkirk's Scott Bain has been added to the squad in Gordon's place.
Speaking after the defeat, Gunn admitted his disappointment at conceding three goals and said he would review his performance to identify where improvements could be made.
