The big match is coming up tonight, and everyone is getting excited to see the clash between the reining Premier League and La Liga champions.
Madrid manager Jose Mourinho will not underestimate City. He was present when City played against Queens Park Rangers earlier this month.
Mourinho believes that there are two players who are a clear threat to Madrid: Carlos Tevez and Mario Balotelli.
According to Yaya Toure, Madrid's midfield is also filled with stars. He said there are three key players in Real Madrid, namely Xabi Alonso, Sami Khedira and Mesut Ozil.
In addition to the names mentioned, of course there are some other players that will play a key role. Sergio Aguero is expected to travel with the team (though he may not get any playing time), as is David Silva. Then of course, there is the biggest superstar out of them all: Cristiano Ronaldo.
