Sunderland have returned from their pre-season tour of South Korea and speculation that they will now make moves in the transfer market is increasing.
Martin O'Neill has already stated his desire to add strikers.
But, Aston Villa forward Gabriel Agbonlahor has dismissed speculation that he is set to move to the Stadium of Light.
Sunderland have also been linked with a move for Steven Pienaar but face stiff competition for his signature.
A source close to Ahmed Elmohamady has also revealed the winger is looking to stay at the club and fight for a first-team place.
