Yeah, I've defended Gundogan non-stop on here but he was not good yesterday, and I think if people rewatched the game they'd pick up on it.
He's to blame for the penalty, pulling out of a standard tackle to stop the attack at their box, and it wasn't the first time he did that yesterday, but more importantly he was barely involved at all until just before the assist, and then when KDB came off.
It wasn't that he was actively poor, and making mistakes on the ball (possibly why it's been overlooked) he was just invisible. His touches and passes were miles down on his normal figures, he spent a lot of time just filling in blank space because Fernandinho and Mendy were doing what he usually does in recycling the ball, and because Foden pushes so much higher up than Silva, he doesn't get involved in those sessions of knocking it between each other and building up.
He just did not recognise that he was a spare man at all, he could and should have destroyed Atalanta by pushing 10 yards further up, but he just watched the game go by until it was over.
Part of me just thinks he's completely unnecessary in that team. The CB pairing was more than good enough at building up from the back, the LB at Mahrez were in midfield so often they helped press and retain possession for the 8's and Foden & KDB are such attacking threats, he can't play the role he sometimes does getting into the box.
