Manchester United v West Brom preview

A United statement read: "Juan has had surgery for a groin injury".

"I don't know how but both central defenders got injured in the English camp even before the match", Mourinho added.

Captain Wayne Rooney returns for Saturday's Premier League game against West Brom (15:00 BST) after recovering from a knee injury.

Ibrahimovic has surpassed expectations in his debut season in the Premier League after joining on a free transfer from Paris Saint-Germain past year.

But his injury means he joins a growing list of absentees as United head into a crucial stage of the season.

Mata's news follows that of "long term" injuries as Mourinho termed it to both England worldwide defenders Chris Smalling (calf) and Phil Jones (toe).

"We want people that if I call some guy or if Mr Woodward calls some player or some agent, we want people who are immediately engaged, immediately dreaming about coming".

Rooney hasn't played since the 1-1 draw with Bournemouth on March 4 after suffering a training ground injury with Jones and Pogba limped off with a hamstring injury in United's UEFA Europa League win against Rostov on March 16.

"They have to be resilient, they have to be professionals", Mourinho said.

It looks straightforward on paper, but United have struggled at home against "lesser opposition" this term and in West Brom they face the best of the rest. "But I think one day I will be there so I can not be very critical". We lost four, I think [Paul] Pogba is also out, that's five, so we are a bit in trouble.

United manager Jose Mourinho revealed on Friday that Jones and Smalling won't be back in action for a prolonged period.

The Baggies are enjoying one of their best Premier League seasons and now sit eighth in the table, having surpassed the 40-point mark that is typically seen as the benchmark to secure survival.

"The important players are the ones that are ready to play and the ones I trust and the ones who are going to give us everything tomorrow to try to keep us in the fight for the top four".
