I think the hype that surrounded him when he first broke through has done him no favours. Right now he is still potential and needs games to develop, but sadly it doesn't look like happening any time soon. I think, last season when we played Hearts at Ibrox (Diouf's debut game), he came on and played behind Jelavic for the last 20 mins, and he played well. Linked well with Jela. Since then, he was moved back out to the left where he is in-effective to say the least. I wouldn't be surprised if he was loaned out or sold, and then goes on to excel wherever he ends up.
