Sunderland boss Steve Bruce has revealed he will be watching England's friendly against Ghana with trepidation amid fears of injury to his players.
Ghana, with three Black Cats players in their squad, have travelled from Kenya to London via Congo-Brazzaville for Tuesday's game at Wembley.
"It's my biggest worry, I hope they all come back from the international break injury-free," Bruce told BBC Newcastle.
"Make no mistake, the Ghanaians will be extremely tired from their jaunts."
The Black Stars were 3-0 winners in their trip to Congo-Brazzaville on Sunday.
Bruce's Sunderland squad has a host of players on international duty, including Danny Welbeck who was called into the England squad on Tuesday to face Asamoah Gyan, John Mensah and Sulley Muntari for Ghana.
Meanwhile Bruce's fears have been heightened by an ongoing injury list at the Stadium of Light this season, which has seen long-term injuries to players such as Michael Turner, Lee Cattermole, Fraizer Campbell and David Meyler.
"We've trained players physically well, we do everything.
"The thing that's happening with all the injuries is that they're happening in games.
"If it was happening in training, then we'd analyse whether we're doing too much or not doing enough, we're looking at that, but there's nothing conclusive.
"I've asked every question and overturned every stone to see if we can try to stop this if we possibly can."
Sunderland travel to Manchester City in the Premier League on Sunday.
