The fomer Barcelona captain and six-time Ballon d’Or winner, 34, joined PSG on a free transfer last week after leaving Barcelona because of their financial difficulties.
He has yet to play a game since winning the Copa America with Argentina but is in full training with PSG.
“We haven’t decided the squad yet, we will assess whether Messi can be a part of it. Everything is positive. There is a good atmosphere in the squad and he has settled in well and quickly. There is a very good feeling.” Mauricio Pochettino said.
“Mbappe is our player and I want him to be here this season,” said Pochettino.
“He has another year left on his contract. Even if he doesn’t renew it, he is still a PSG player and we are very pleased with him, and from what I can understand he is pleased with us. He is very calm and preparing well for tomorrow’s game as the manager Pochettino played down rumours France forward Kylian Mbappe could join Real Madrid this summer.
