Manchester United will miss Paul Pogba, says Henrikh Mkhitaryan

London: Manchester United may struggle to maintain their explosive start to the Premier League season if injured midfielder Paul Pogba is out for long, the club's playmaker Henrikh Mkhitaryan has said.

Pogba hurt his hamstring during United's Champions League win over Basel last week and will undergo further scans to determine his recovery period.

The France international, who captained United against the Swiss champions, limped off in the 3-0 win and some reports have suggested he could be out for 12 weeks with a muscle tear.

But manager Jose Mourinho has said the nature of the injury would not be known until after the results of the scans.

United thumped Everton 4-0 over the weekend with Marouane Fellaini stepping in for Pogba but Mkhitaryan said the club would miss Pogba's creativity that has help them script big victories this season.

"It's hard, because he's a top player for us," he told France's SFR Sport. "It's going to be very difficult, but the coach knows how to make up for that and we're going to help him come back stronger."

Mourinho's side share top spot in the Premier League table with Manchester City and have 13 points from five games. Both Manchester clubs have scored 16 goals and conceded only two.

United host Championship side (second tier) Burton Albion in the third round of the League Cup on Wednesday before travelling to Southampton in the league on Saturday.
