I think he tried, had his moments and ultimately came up short. But that's all in the past now.
As a side note though, is anyone else a little annoyed at his leaving statement? May be petty, but surely he should be thanking US first and Newcastle second. We gave him his initial chance(s) etc.....surely his one single season (on loan I might add) should be secondary. Not sure if that's just my opinion or if anyone else picked up on that small point.
