You mean the 3 vs 2 counter where the forward was offside? Not an easy situation but think they did ok and it was good enough line to set him offside as we saw. There were also situations where he cleared up behind the other defenders, like it should be, so definitely think he did his part. But of course he is just one part of the team, like everybody else. I would say he was pretty good last season and the season before he was starting most games and we finished second in the league. The point is this you can’t expect much more from a third CB than to be part of a team that wins again and again even though it is the third choice who is playing.
If you want Varane level, who would recommend? There are not many of that level and none of them would be third choice.
