Yes but if Schar is no longer with the club / retired / incapable / whatever, who is Thiaw's backup?

Well that will be further down the line, eventually Thiaw will be the starter and Schar will be backup when he's no longer capable of playing as much as he does but still a decent level

The club captain? What his name again? 😅

He's miles away from the standard we want, let's be completely honest
