Sunderland boss Martin O'Neill admits he wants to add to his squad this summer.

With little left to play for in the remaining four matches of the campaign, O'Neill may look to give his younger players an opportunity before bringing in fresh faces in the summer.

"I'm going to have to look at strengthening the squad," said O'Neill.

"In the last couple of games we might be able to look at some of the younger players and see how that works out, so we have a viewpoint on them for the summertime.

"But I still feel we need to strengthen."
