Spearing has hailed his mate Kelly and says the defender deserves a chance to earn a full England cap.
"I have come through the ranks with Kells [Kelly] and it is great to be involved in the first team squad together," said the midfielder.
"He would deserve an England call-up. He was on a roll last season when Kenny took over and was just unlucky to get injured at West Ham.
"He got a bit of banter from the lads about the way he went down, but with a hamstring injury there is nothing you can do and it does take time before you are ready to come back.
"He showed again at Arsenal exactly what he is capable of doing and I think he will go on to better things."
