Swansea were the toughest opponent you faced, they threatened you in a way no other team did.
Didn't watch the cup game but I think this is the first time Pep changes the formation, I mean tactics. This time Sagna was more of a classic RB while Kolarov was closer to a 3rd CB. Instead of the multi role they were doing (SB when defending + CM when attacking). Maybe playing Gundogan who is different than Kevin (who this time played as a real AMF) forced this change. You did good but you found too much difficulties with Swansea.
