This can be also only clickbaiting.
Raiola already said the past year "Paul will leave Manchester".
I think there is no chance he will stay with Red Devils.
For him to actually leave, there must be someone willing to pay that huge contract he will be demanding. He has started this season really great but overall his United performances have been below par and the clubs that are interested will track how he'll play in the following months.
Pogba on a free transfer looks like a great deal but it is not that simple - he'll still cost a fortune. Extending with United might be the best option he will receive - so it would not surprise me at all if he stayed there.
Which club is interested in Pogba's future contract, especially by paying such an expensive contract fee, is it Real Madrid or PSG?
Pogba is the type of person who wants a big salary even if his game is below the standard than before if the salary is still high it is possible to stay with the red devils, unless there is someone who demands more like you say.
To be honest Pogba's performance at Man United was not so bright but I don't know what if Man United had changed coaches and the possibility of Pogba being able to play well again, because for me Ole Gunner can't use Pogba as well as possible.
