Had a brilliant game in my opinion. On the ball, he is just brilliant. Needs to make those runs though, specially when he is playing as a no.10. But that aspect is going to come with experience.
Players not positioning themselves properly specially when that player is a striker is a massive part of the problem. Players looking to be more interested in picking fights than actually scoring is another part of the problem. And Diego has been doing both of these things on a consistent basis. He might have got the winner today but it is just another false Dawn.
