Real Madrid: Real Madrid knows what it needs to do, and it isn't going to play for the 0-0 draw. That's a death wish against a Barca team that can score at will. They need to remain composed, look to go on the counter with speed and feed Karim Benzema. Expect it to be physical, expect a lot of cards and also anticipate set pieces playing a huge role.

Barcelona: Can Barca figure something out defensively against Vinicius Junior? The young Brazilian drove Barca wild in the first leg down the left. He was quick, his decision making caught the Barca defense off guard and he really put a target on his back for this game. Expect Barca to play a bit more cautious in the back, perhaps with the right back, likely Nelson Semedo, not going forward as much.
