Questions over Pogba's future have been a troublesome undercurrent to an inconsistent season for United and Solskjaer.

The midfielder has been persistently linked with a return to Juventus or a move to Real Madrid, while agent Mino Raiola has encouraged the speculation with comments in the press suggesting a move would be in the player's best interests.

Matters reached a head when Raiola launched a social media tirade against Solskjaer after being criticised by the United manager, although he later moved to reduce tensions by offering to "reach out" to the Norwegian and suggesting Pogba could sign a new contract.

Pogba's injury problems have not helped the uncertainty over his plans – the France star has played only eight times in all competitions this season due to ankle problems, and Solskjaer stated last week that he was "nowhere near" a return.

Former United star Van Persie thinks Pogba's prolonged absence has only exacerbated the rumours about whether he will stay at the club, and he wants the player to go public to make his clear whether he is happy at Old Trafford.

The ex-Netherlands forward also thinks Pogba should state what he considers to be his best position, as Van Persie believes there has been unjust criticism of the 26-year-old, who has played in different midfield roles since returning to United in 2016.

"It's very difficult. With Pogba, it's an interesting situation," Van Persie said. "Pogba, in my opinion, is a world-class player, he has proven it over the years. He has it all.

"But first, I think with him, and that's after a couple of years now, I think he should come out and he should say what his favourite position is. If that's done, then people can judge him based on this position. Now, I don't think people really know if he's a six, if he's a number 10... that's a big difference.

"I have the feeling people judge him a bit unfairly. They expect 20 goals, they expect 20 assists, they expect Pogba to make Manchester United champions. But, is he a six? If he's a six, then you cannot expect 20 goals. If he's a 10, maybe 12 to 15 goals. So, it's not really fair on him because it's not really clear.

"Then, you have the second subject: is he happy there? There's constantly rumours, you have the agent constantly giving interviews, you have the coach answering questions almost every day, every week. There's a lot going on beside the main event, and the most important thing is football.

"I know how it works, especially if you're injured. People can't judge you on your game, so they start to talk about other things.

"I think for Pogba, and Manchester, it would be best to… I don't know, do an interview together or something, together with the coach, and just say, 'Listen: this is what I want, this is where I would like to play – judge me on that. I'm happy, or I'm not happy, or whatever'. Now, it's a lot of questions going around."
