He did have a good Euros, but that was because Denmark used him as the team's focal point - he wouldn't have the team built around him at Spurs, for the simple reason he'd be back-up behind Ade and Defoe.
I wouldn't take him with our current circumstances, because a) he's a twat, b) him and Adebayor don't get on, and c) he's only going to be any good if he's a regular starter. He actually has a fair amount of ability as a player and would fit into Adebayor's role pretty well, but he doesn't suit Arsenal's normal style of play, much like Chamakh.
