Sigurdsson generally was quite disappointing, his all round contribution was very poor and unless he managed to score there was absolutely no point on him being on the pitch. Not really sure why, just didn't seem to work for him. Good enough player to be at that level IMO, maybe just wrong club at the wrong time.
Competing against about 7 other attacking midfielders for a place in the side and then for some space and chances when on the pitch. They're in the same mess now.
