Paul Pogba faces the prospect of weeks on the sidelines after a hamstring injury ended his night as Manchester United captain abruptly in their opening Champions League game on Tuesday.
The central midfielder pulled up after just 19 minutes against Basle at Old Trafford, appearing to overstretch while making a challenge.
Pogba immediately signalled to the bench and headed straight down the tunnel shaking his head in disappointment.
His replacement, Marouane Fellaini, headed home United’s opener soon after being introduced.
It is the second hamstring problem 24-year-old Pogba has suffered in six months. He also departed early against Rostov during the Europa League knockout clash in March.
Pogba returned from that strain earlier than expected, back after three weeks, but it remains to be seen how severe this latest issue is.
Jose Mourinho’s side are in the midst of a hectic schedule, with five games to play in the next 17 days before October’s international break. The run includes Premier League matches against Wayne Rooney’s Everton, Southampton and Crystal Palace, plus a Champions League trip to CSKA Moscow. Mourinho had planned to rest Pogba for the League Cup game with Burton Albion next Wednesday but this injury could leave Mourinho short on creativity in midfield, with Fellaini, club captain Michael Carrick and Ander Herrera — absent from the squad altogether last night — the options to deputise alongside Nemanja Matic.
