Solskjaer said at today's Champions League presser: "He is ready to play and of course it's special for him to play against PSG, his old club where he is the top scorer, so that will affect him mentally.
“But from knowing him, that will give him energy. He is so professional. And he will work on his mindset today to get ready for the game.
"The best players can put those things aside."
