Manchester United boss Ole Gunnar Solskjaer believes that Alexis Sanchez has a point to prove against Barcelona.
The Chilean attacker, one of the highest paid players in the world, has struggled to fulfill his potential since arriving from Arsenal last January.
He has recently recovered from a knee injury to take his place in the squad for the quarter final second leg at the Nou Camp.
And Solskjaer thinks he will have something to prove if he is selected.
"Well of course that memory of PSG will help the players," the Norwegian told a press conference.
"As a team we know that we can turn things around - it is not that long ago and we are one goal better off. [But] Barcelona is a difficult prospect.
"Fitness-wise [Matic and Sanchez] are available.
"Of course, for Alexis who has been here and played here it is a big night. When he is on the pitch he wants to prove a point as well.
"Let's hope he can end the season great for us.
"We are playing games that United are used to. We are still challenging for a semi-final.
"Let's hope Alexis, when he is on the pitch, can be happy with his performance."
