Mourinho opted to drop Pogba for a number of crucial fixtures earlier in the season and has publicly told him he must be more consistent.
Pogbas agent, Mino Raiola, is said to have made contact with several European clubs about the possibility of a move at the end of the season.
But the French midfielder, who returned to United for a fee of almost £90million in 2016, says he is very happy at Old Trafford and focused on finishing the season on a high.
Asked to describe his relationship with Mourinho, Pogba told Sky Sports: Its good, very good. Hes the coach, Im the player. He does the coaching, I do the playing.
Im here and very happy. I give my best for the team, for myself Im happy because we are in a final and I want to finish the season very well.
Pogba admits that being dropped to the bench was not something he was used to but says he will use the experience to become a stronger player and person.
He said: Its not something Im used to, but everyone has to go through this.
It makes you stronger and makes you realise you have to work hard, because anything can happen. Its affected me in a good way.
When you go through it, you just have to work and keep believing in yourself and respond on the pitch.
France international Pogba also insisted that there is more to come from him in a Manchester United shirt.
You always want to be at the top every game, to improve every game and I think I am still improving, he added.
I can still do better. I am not young but I can still improve, learn and get more experience. I will get better and better during the next year.
