Celta Vigo midfielder Tucu Hernandez says they'll leave everything on the pitch at Manchester United on Thursday night.
Celta go to their Europa League opponents having to overturn a 1-0 deficit.
Tucu admits he is carrying a back injury, but says: "In these games there is no pain, I'm not going to let this opportunity pass, I want to do my best and contribute my bit to help the team, I'm good to play.
"We already know what we are facing and tomorrow there is nothing between the teams. We can win. It is the only thing that is spoken in the dressing room."
