Harry Wilson’s knee injury is expected to heal for the World Cup, according to Marco Silva.

The 25-year-old sustained the injury during a pre-season friendly against Aston Villa played behind closed doors.

Wales' first World Cup match is against the United States on 21 November.

Silva said: “It’s difficult for us to give you a timeline really because different things can happen.”

His team will play Liverpool in their first Premier League game since earning promotion on Saturday.

We will see how long it can last if it gets less, which is very good for us.

‘He’s a big big piece for us, what he can give us in certain games, the profile he can give us, completely different things from the others,’ the player said.

I believe he can assist us in ensuring that we are in the proper conditions there even before the World Cup.
