Pogba reveals why he has under-performed for Manchester United this season

- Paul Pogba is yet to hit top gear for Man United this season

- The 25-year-old and Mourinho have been involved in a row

- The Frenchman has been linked with Juventus and Barcelona

France star Paul Pogba has blamed his recent form with Manchester United on his late return from the World Cup.

The World Cup winner returned of United's training camp days before the start of the new Premier League season.

United kicked off the new season with a 2-1 victory over Leicester City at Old Trafford with Pogba unable to play 90 minutes due to a lack in fitness.

The 25-year-old's difficult start to the campaign continued as the Red Devils lost two of their opening four matches, putting much pressure on the Frenchman.

Pogba has called a truce with Jose Mourinho after agreeing to remain with United in January - but admitted that circumstances could change later in the season.

When asked if he was "fed up" with all the speculation in England about his relationship with United manager Jose Mourinho, the attacking midfielder said: "It's not me who's talking.

"I'm trying to work on myself physically. I got back late (from the World Cup), so I'm trying to perform as well as possible.

"I'm just trying to do my job and for the rest there'll always be talk."

The former Juventus star was speaking after France's 0-0 draw with Germany, however those comments came after an earlier interview he gave to Sky Germany that did add to the uncertainty surrounding his happiness at Old Trafford.

"My future is currently in Manchester," he said. "I still have a contract. I'm playing there at the moment, but who knows what will happen in the next few months?"

On Mourinho, he added: "We have a pure coach-player relationship. That's how it is.

"One thing I can assure you: I will always give 100 percent, regardless for which coach. I always give everything for United - I cannot say more."

The United academy graduate Pogba returned to the Premier League side after four successful years with Juventus for a then world-record transfer fee of £89million in 2016.

But he has failed to live up to the price tag and Mourinho's frustration with him has been obvious.

Pogba was a key factor in France's success at Russia, and that is why he has been repeatedly linked with a return to Juve and Barcelona.

Meanwhile, eagleee.com had earlier reported that Manchester United midfielder Paul Pogba has told the club he wants to return to Juventus and link up with Cristiano Ronaldo.

The unsettled France international has endured a frustrating start to the new Premier League season.
