The Brazilian midfielder insists that the players are fully focused on the task in hand, though adds that it is just as important to enjoy an occasion as big as Wednesday night.
"These are the games you want to play in. We know we have to be very focused but it's also important to enjoy games like this," he told ManUtd.com.
"It will be a hard game. Of course, Madrid are a big team but we are a big team too, with quality players and experienced players. We are playing well and looking forward to it.
"Concentration is going to be very important. Everyone knows it's not a normal game - it's a big match - but you have to try and play your normal football and work hard together as a team. Hopefully we can come back with a good result and finish the job at Old Trafford."
