HARRIERS' FA Cup opponents Sunderland are set to hand debuts to South Americans Santiago Vergini and Oscar Ustari in tomorrow's Fourth Round tie at the Stadium of Light.

Black Cats boss Gus Poyet expects the Argentine pair to both play a part at the Stadium of Light on Saturday as he makes changes from the side which defeated Manchestet United on penalties in the League Cup on Wednesday night.

“They are going to make their debuts if everything goes alright until the game,” he told Sunderland's official website.

"It’s going to be great for them to feel the stadium, the pitch, the football and the speed in a cup tie where we are the favourites and need to win.

"It will be a good opportunity for them and also for the fans to get their first impressions.”
