Chris Wilder has defended Sheffield United's tactics in stopping Wilfried Zaha in Sunday's 1-0 win over Crystal Palace.

Wilder was asked aboutZaha's complaints that he had been singled-out for special treatment by some of his team.

"It's still a contact sport," Wilder said.

"Players are still allowed to make contact with each other and they should be allowed to make contact. That's part and parcel of what we do."
