He said: "Of course I'm committed to the club. I'm a Sunderland player until they tell me I'm not.
"I'm expecting a very busy summer in the transfer market. With the takeover from Ellis Short, hopefully he can bring in top-drawer players and that's better for us.
"The better players he brings in, it's going to make us better as players. I'm sure the fans will be looking forward to that as well."
