The amount of matches Manchester United have played in April appeared to eventually catch up with them on Sunday afternoon.

Their most recent clash with Swansea at Old Trafford was the ninth time Jose Mourinho's men have been in action over the last four weeks and it showed in a lethargic performance against Paul Clement's side.

Gylfi Sigurdsson's excellent second-half free-kick ensured the Swans came away with a point after Wayne Rooney had earlier converted a penalty on the stroke of half-time.

To make matters worse, the Red Devils' only fit recognised centre-back, Eric Bailly, picked up an injury midway through the second period and had to be replaced by Matteo Darmian.

That came after Luke Shaw picked up a knock of his own with just 10 minutes on the clock, with Antonio Valencia his replacement.

The nature of Shaw's injury was unclear, but he didn't receive much sympathy from his manager after the final whistle.

Mourinho has publically criticised the English left-back on various occasions this season.

In recent weeks, Shaw has managed to work his way back into Mourinho's good book but their relationship has appeared to take another hit.

In his post-match interview with BT Sport, Mourinho seemingly took another swipe at his player.

"I don't know about the injuries," the Portuguese boss said.

"I think Luke Shaw's must be a big injury, because to leave the pitch after 10 minutes I am expecting a very big injury."

However, given his limited defensive options right now, Mourinho will need all hands on deck if Man United are to salvage something from their campaign.

A second draw in four days has cast further doubt on their chances of finishing in the top four and places far even more importance on their upcoming Europa League semi-final.

On their other injuries, Mourinho was reluctant to discuss the chances of Phil Jones or Chris Smalling being back in time for Thursday's trip to play Celta Vigo in Spain.

He added: "I prefer not to speak about Phil Jones and Chris Smalling. I prefer to speak about Juan Mata giving everything to be available. I am grateful for that.

"We will give everything on Thursday. That is sure. Whether we go to the final or not doesn't matter, I am really happy with the guys.

"We lost players and we lost points, so yes today was a bad day. We did not look tired and exhausted, we are tired and exhausted. You cannot isolate the performance out of the context.

"This is the ninth match of April, it is not human. We have a squad of 22 that is reduced to 13 or 14 players. The players are very tired."
