There was something about his body-language that seemed to suggest he wasn't entirely happy here. I don't recall him giving any interviews, no comments in the press from him expressing his hopes & desires to force his way into the reckoning at our club, his pre-season goals he scored recently ... no expression on his face, little interaction with team mates, nothing in fact.
I think Warnock looks for character in his players - maybe Saadi didn't have that something about him, on the training ground and in the dressing room?
