Even without the goal that's the best 45 minutes I've seen Sangare have, helped perhaps by the fact that Aaronson is a whiny lightweight. Still, he's been in the right place pretty much every time, recovered well, and moved the ball quickly and effectively.
Unfortunately I'd hook him at half time, because as Chic says it seems likelier than not that he picks up another yellow. Leeds are very divey and while the ref so far has done a decent job of recognising it, at some point they'll sell one.
