Yes the defence was exposed but he didn't help himself, there was no reason at all to go to ground for the 3rd and 4th goals, it's a habit that he needs to eliminate, Akanji was fine he was our best defender out there, Walker and Gvardiol were poor too.It's funny when people say Ruben, Akanji had a bad game.. but the actual fuck up is further up the field requiring Ruben and others to be the last person who has a shot at defending.
Did he make a mistake giving away the pen? Yes but the ball was given away too cheaply by our midfield all fucking game.
We literally gifted Chelsea 3 of their 4 goals!
Can't do anything about the corner but the other 3 were mistakes on City's part!
