The only hesitation in letting him go for me would be the fact we've put two years into him.
I don't think he has hit the heights he should have - even when we were playing well last season. He often skips past defenders then *almost* gets the ball away but ends up losing it - it's quite strange. For me, he's still an almost-there player, not quite good enough to be taking up a precious import spot. Might be harsh; but if we want to win the league we need at least 3/4 of the imports to fire.
