He's obviously a talented player, but he seems very injury prone these days plus,
a decent point that has been made before is that you have to accomodate him in a side because of his tendency to run where the fuck he likes and totally distort the shape of the team.
In short, England would have to build the team around him, making players understand that they have to fill the gaps he leaves, and I'm not sure that he brings even nearly enough these days to make that worthwhile.
