If your evaluation of a player is affected by one game then i don't know what to say, nevermind that it wasnt even a penalty and was an attempt to control a high ball (Pogba's handball was actually a penalty and he managed to dab while giving the handball
). Notice i'm not criticizing Smalling for his shambolic performance against Chelsea or Arsenal because using single games to assess a player is moronic.
As for the last sentence, im not sure if that is supposed to be some sort of vindication for what you've said, but it's a nothing statement. Bailly and Rojo have gotten the most starts and minutes at centre back and both of them would be even further ahead in the pecking order had it not been for AFCON + injuries. The only reason Smalling even gets a sniff for the final is because Bailly and Rojo can't play in the final
