Manchester United fans must have feared the worst when their Champions League match on Tuesday was stopped inside 19 minutes owing to a Paul Pogba injury.

Their worries are valid as the 24-year-old star man was reportedly seen leaving Old Trafford on crutches.

Jose Mourinho now fears Paul Pogba will miss a "few weeks" with the hamstring injury that took the shine off their victorious return to the Champions League.

"I don't know (what the severity is)," Mourinho told MUTV. "I just know from experience it's a muscular injury.

"In my experience, muscular injury stops you from playing for a few weeks, I think.

"It looks for me too (like a hamstring injury) but I haven't spoken yet to the medical department.

"Squads are for this, squads are for injuries, squads are for suspensions. We don't cry with injuries.

"So, if no Paul for Sunday, we have (Ander) Herrera, we have (Michael) Carrick, we have Fellaini and we have (Nemanja) Matic."

United won the match 3-0 but Mourinho was not so impressed. He expects United to be more switched on against Everton at the weekend.

Substitute Marouane Fellaini headed United into a deserved first-half lead and compatriot Romelu Lukaku followed suit early in the second period with his first goal in the Champions League group stage.

Marcus Rashford came off the bench to net his first goal in the competition and wrap up a 3-0 win against Basle.
