Sunderland boss Martin O'Neill is trawling the free agency market.

O'Neill is seeking to strengthen every area of his squad.

He said: "It is not just strikers I am considering - I will look at any position at the moment, just to see who is available.

"In truth, you know you are not going to get top-quality signings if another club elsewhere has decided not to renew a contract, but I cannot turn my nose up at anything at the minute."
