Pogba has yet to prove that he is worth the price of his fee plus the salary he earns, we will see him in another league next season.
Lewandowski would be very interesting to see him change of scenery, if he definitely goes to Barcelona I would like to see how he adapts to a new league and if he manages to impose conditions as he did in Germany, we will see because he is already 33 years old.
Mbappe in my opinion should look for a new challenge, staying at PSG for me would not be the right thing to do, he should go to a better more competitive league, to see him in the Premier would be a dream but he will probably go to spain
