Leon Britton doubt for Manchester United Clash

The 34-year-old midfielder is suffering with a back strain.

"Leon has been struggling with his back over the last couple of days so he's missed two days of training," said head coach Paul Clement.

This could pave the way for £11m signing Roque Mesa to make his first start for his new club if Britton doesn't recover in time.

"I'm not sure yet whether he'll rejoin training before the game," Clement added.

Swansea started their campaign with a 0-0 draw away to Southampton while United beat West Ham at home with a convincing scoreline of 4-0.
