'Pogba - not Mourinho - must take responsibility for Man Utd star's performances' - Rooney

The Red Devils' all-time top goalscorer feels the France international has to lead from the front if the Old Trafford side are to challenge for titles

World Cup winner Pogba was criticised for his performance against as the Red Devils slipped to their first defeat of the season on Sunday.

Pogba - who has captained United in each of their first two Premier League games of the campaign - responded to the result at the Amex Stadium by bemoaning his side's attitude and suggesting the Old Trafford outfit had not sufficiently prepared for the encounter.

Such comments only fuelled speculation that he and manager Jose Mourinho have fallen out amid reports that Pogba is keen to leave for .

Rooney, though, believes that Pogba - who arrived back in Manchester for a Premier League record fee of £89.3 million ($115m) - is the only person who can ensure he meets the expectations that came with his price tag.

"He is a fantastic player but he has to do it for himself," United's all-time record goalscorer and current forward told CNN World Sport.

"If they’re going to win the title, he’ll be the main player in terms of them doing that.

"You hear a lot of people saying Jose Mourinho needs to get the best out of him but he needs to do it for himself and prove he’s at that level to help Man United."

United will be looking to bounce back with victory as they host at Old Trafford on Monday.
