So far, it's honours even. A 1-1 draw in La Liga effectively handed Barcelona the league title while a 1-0 extra-time win saw Real Madrid clinch the Copa del Rey.

Now it's time to decide the Champions League, with the first-leg taking place tonight at the Bernabeu. The usually outwardly confident Jose Mourinho concedes the game is too close to call. "There are no favourites in semi-finals," he said. "Maybe after the first leg we can talk about one team having a slight advantage."

Here, we bring you some of the best ever games between the two sides, find out how El Clasico earned it's reputation and look ahead to the semi-final.

Wednesday 27 April: Champions League semi-final, Bernabeu
