"Hatem was always a good player, but he just didn't understand what it takes to be a success in the Premier League. I've given him countless chances and invested a lot of time, but the penny just wouldn't drop when he was with us. It appears it has finally dropped now though, and I believe Hatem will be the first to admit I was right in persisting with my advice. He's obviously now reaping the rewards of years of hard work on the mental side of his game."
