First and foremost, he isn't fit and hasn't been all season..barring the first couple.
tactically speaking, It's the fact that we don't dominate the midfield away from home. All our attackers suffer from it, only Bellamy and Tevez can mask over this fact by running around a lot.
At home, we win the midfield battle the majority of the time because the opposition's mentality is different. This means our attackers are further upfield and the majority of Robbie's touches are around the penalty area. Away from home, he touches the ball just as much but he's on the halfway line and his tricks and feints are useless there...as the area is too crowded and the centre of midfield is too powerful for a guy like Robbie. IF we had midfielders who dominated the game, it would allow our attackers to play further forward without worrying about being too far from the centre of midfield. In turn this would allow Robinho to play to his own strengths and it would allow him time on the ball around the opponents penalty area. It's quite simple.
But anyway fuck all this logical debate. I'm off to have a wank over the fact De Jong clatters people and Bellamy doesn't stop running. Then i'm going to play Football Manager and scout the next boo-boy. Ageuro most probably...apparently the kids a bit special.
