Interim Swansea City manager Alan Curtis has backed captain Ashley Williams to get the better of Manchester United skipper Wayne Rooney when the two teams meet on Saturday.
Swansea have been something of a bogey team for United under Louis van Gaal, and Curtis believes a strong performance from Williams at Old Trafford could send the Premier League visitors - just two points clear of the relegation zone - onto another famous result against the 20-time league champions.
"Ash has got a big-game mentality, Curtis said.
"We played last Saturday and Monday and we had to take Leon [Britton] and Angel [Rangel] out of the side at Palace to try to protect them for games down the line.
"Ash has played against Rooney before, and they will face each other in the summer.
"Rooney has come in for a little bit of stick lately but he's been a great player and still is.
"Manchester United need Rooney to be at his best. Like Ash, he's their leader and it will be a big tussle between those two."
