For any Barcelona player or former player, going at it against Real Madrid is extra motivating as they are always eager to beat them in any shape or form. Borussia Dortmund has the amazing task of ending that 33-match unbeaten run at the Santiago Bernabeu, a stadium that Bartra knows perfectly as he's played there many times in past seasons.
Talking to UEFA.com, Bartra said: "It's great to come to Bernabeu, especially with the rivalry with my old club and then to come back here with Dortmund to play for first place in the group in the Champions League is great. It is one of the best games you could have in Europe right now and for me it'll be very special. Madrid are a dangerous side in attack. We aren't thinking about favorites. We want to play a good game, to win the game. We've had a good group stage, winning all the games bar the previous meeting with Madrid and I think we have a side that can face up to Madrid.
"Getting three points in Madrid is difficult and we'll have to be at 100 percent if we are to take the victory from it. It's a game that asks a lot from you, both in terms of defense and attack. They're very highly contested games and you need to be on it mentally at all times. We've played against Bayern, Gladbach, sides that have a lot of quality. Madrid have a lot of world-class players who all bring their own thing to the game both at the back and going forward."
He added: "We can change our system. We've changed up a lot but I've felt very comfortable since I've arrived playing in the coach's style. The boss will decide tomorrow how we set up in order to get a result. Whatever the setup we will have the right attitude in order to take a positive result and that's the most important thing."
