He said: “It has been a difficult period. It has taken quite a while to get back to full fitness, but that is normal.

“I am 100 per cent OK and looking forward to playing in the rest of the season. Hopefully, I can have a good game and make the fans really happy.
“The supporters have stuck with me through some difficult times, and it would be nice to repay them.
“Sunday is a very good opportunity for me to do that.”
