To me, that’s a pen. Yeah, it’s ‘minimal contact’ or whatever but he’s tripped him. The fact Ouattara was booked for diving is even more egregious than it not being a pen.
I think Doku is one of my favourite non-City players to watch as a neutral. Proper winger that lad. Gets the ball and just wants to take players on and create something. He might lose it occasionally but he’s one of the best dribblers in the Prem and watching him skip past players is class. Ndala looked very similar in the early games he played for us. Unfortunately, he’s lost a bit of confidence since he came back into the team.
