Paul Pogba has blamed the inconsistency in his Manchester United performances on his late return from the World Cup.
The midfielder was part of the France squad that went all the way and claimed victory in Russia - but the final took place less than four weeks before the start of the new Premier League season.
United kicked off the new season with Pogba unable to play 90 minutes due to a lack in fitness.
His difficult start to the campaign continued as United lost two of their opening four matches, ramping up the pressure on the Frenchman.
Pogba has called a truce with Jose Mourinho after agreeing to remain at the club in January - but admitted that circumstances could change later in the season.

Asked if he was "fed up" with all the speculation in England about his relationship with United manager Jose Mourinho, the 25-year-old 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."
Pogba 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."

Former United youth player 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 consistently deliver the type of performances a player with that price tag should be capable of and Mourinho's frustration with him has been obvious.
Pogba was a key factor in France's success this summer, though, and there is no disputing his potential, which is why he has been repeatedly linked with a return to Juve or a move to Spanish giants Barcelona.
