This isn't true at all, he is good enough, like I said, some folk had a serious bee in their bonnet cause he never smiled. According to transfer market he played 66 times for us, 17 goals and 9 assists in that time, A goal contribution every 2.53 games.
FWIW, Moult had a goal contribution every 1.48 games, Ryan bowman every 3.18 games, Devante Cole every 2.16 games, Callum Lang every 3.5 games and Tony watt every 2.55 (if my maths is correct)
Now I know that doesn't paint the whole picture, far from it, however I think saying he wasn't good enough for us is even further from the truth.
