Real Madrid v Barcelona

Barca won this corresponding fixture 6-2 last season to all but put that year's title race to bed, moving seven points clear of Madrid with just four games remaining.
That was one of the most painful defeats in Madrid's history, but Barca coach Pep Guardiola has ruled out something similar happening tomorrow.
"The 6-2 is unrepeatable. These things happen once in a lifetime, no more,'' he said.
Guardiola also played down suggestions this weekend's match would be the defining one of the season, although he conceded it is a key game.
"If there were only three or four games to go I would say it is an almost decisive match, but when there are seven left afterwards it's not so much, but it is very important,'' he said.
"It's not a final, but we need to play as if it was one. It's a game where the winner will strike a blow to the other.''
Guardiola will be without Zlatan Ibrahimovic and Eric Abidal through injury for the match, but centre-back Gerard Pique has been passed fit to play.
For Madrid, Kaka is again missing, as are Pepe and Royston Drenthe, but Sergio Ramos and Xabi Alonso return after being suspended for last weekend's win over Racing Santander.
