Jose Mourinho says he will be without at least five Manchester United players for the weekend's clash with West Bromwich Albion.

Zlatan Ibrahimovic and Ander Herrera are out suspended while defenders Chris Smalling and Phil Jones were injured on England duty last week and will miss Saturday's visit of the Baggies.

Star midfielder Paul Pogba sustained a calf issue in United's last match against Middlesbrough and has not come up.

Mourinho is also sweating on Ecuador international Antonio Valencia and Argentine defender Marcos Rojo who will only return from South America 48 hours before the match at Old Trafford.

"We lost four, I think Pogba is also out, that's five, so we are a bit in trouble," said Mourinho.

"I watched Valencia's match yesterday in Ecuador, Marcos Rojo in Bolivia, but they don't arrive until Thursday afternoon.

"If you compare our situation with our opponents, West Bromwich Albion, only one player on international duty.

"They had time to work, time to rest and prepare. It's going to be hard."
