he's nearly 30 years old, if he cant beat a man, finish a chance and cross a ball by now I cant see Pep having much luck.
As pithy as that sounds, he was good in his first season, and clearly it's pellegrini's tactics which didn't agree with him - or any winger for that matter. His half dozen goals and 13 assists in 13/14 were a more than decent return and there's no reason to think Pep can't get at least that much out of him.
Very hard to beat players when the entire defence is behind the ball and you're receiving the ball at the 18 yard line with no space to run into. Get him the ball early, on a counter attack and he's a completely different player.
Same goes for crossing - turns out trying to pick out a 5'8" striker in a box packed with 8 defenders over 6 foot isn't particularly productive. When we attacked at pace and he got behind the defence in 13/14, he could pick out Aguero or Negredo just fine.
