I'll add a RM 4-0 Mérida (remember them?). It was the home closer in one of Madrid's worst seasons in 20 years (we didn't even make the UEFA Cup spots). The reason I rank it is because it was the last home game for Michael Laudrup and, above all, for Michel, who scored a PK and a tremendous volley towards the end of the game. Two of my all-time favourite players.
Two great players. One of my favorite Michel moments is with Spain... remember the "me lo merezco"? Then there is the Michel moment with el Pibe Valderrama... ha! ha! ha!
The win against Manchester Utd in the 2000 UCL stands out for me. They went there as underdogs and put in a spectacular performance, front to back. Really put them back on track as European greats. http://www.youtube.com/watch?v=nUjbVZnK5EI
