The match is underway
Barcelona's starting line-up: Claudio Bravo, Daniel Alves, Gerard Pique, Jeremy Mathieu, Jordi Alba, Ivan Rakitic, Javier Mascherano, Andres Iniesta, Lionel Messi, Luis Suarez, Neymar
Real Madrid's starting line-up: Iker Casillas, Dani Carvajal, Pepe, Sergio Ramos, Marcelo, Toni Kroos, Luka Modric, Isco, Gareth Bale, Karim Benzema, Cristiano Ronaldo
21:30 Both sides are warming up, around 30 minutes before kick-off.
21:15 There are no surprises in Real Madrid's starting XI, with Ancelotti fielding the usual attacking trio of Bale, Benzema and Ronaldo.
21:10 Jeremy Mathieu will partner Gerard Pique in the heart of Barcelona's defence, with Javier Mascherano switched to a central midfield position following the injury of Busquets.
20:20 Barcelona coach Luis Enrique played down the 'favourite tag' saying: "Generally, we have to think that in this type of game there aren't favourites. There is a lot at stake and the two teams have players that are out of this world. He added that he doesn't think that the game is a title decider as there still 10 games to play.
19:30 Real Madrid coach Carlo Ancelotti said: "Being favourites or not depends on your form. At the moment Barca are in better form than us. That aside, it is a very difficult game for both teams. We have confidence because this game gives us the opportunity to return to the top of the table."

18:30 Check some interesting numbers behind tonight's Clasico
18:00 Barcelona confirmed on Sunday that midfielder Busquets has been passed fit to take part in the game after recovering from an ankle injury.
17:00 The game may well be decided in the midfield, where Madrid has finally managed to match Barcelona by bringing in strong passers like Toni Kroos and Francisco ''Isco'' Alarcon.
Madrid will be without James Rodriguez with a broken foot, while Javier Mascherano should seamlessly fill in for Barcelona in place of injured stopper Sergio Busquets. The question then for Luis Enrique is whether to play Jeremy Mathieu or Marca Bartra alongside Gerard Pique in defense.
16:30 Not surprisingly, Madrid's troubles coincide with a dip in form from Ronaldo.
Ronaldo once held a big lead over Messi in goals scored in the league, 23-13 through 15 matches. Messi has since gone on a scoring streak with 19 goals in the last 12 games, while Ronaldo has notched five. Messi now leads Ronaldo 32-30 in the league and 43-41 overall.
16:30 Messi is back to playing at a level reminiscent of his best days under former coach Pep Guardiola.
Luis Enrique has moved Messi back to his original position on the right side of Barcelona's attack, and Messi is flourishing both as a scorer and in his newfound role as the team's best passer and playmaker.
16:30 All eyes tonight will be on the Ronaldo-Messi rivalry.
16:00 Barcelona appeared to be on the brink of a breakdown following a loss at Real Sociedad in early January. That was followed by a chaotic week that included the firing of its sport director and president Josep Bartomeu calling for early elections in the offseason.
The team has responded in incredible fashion. Barcelona has reached the final of the Copa del Rey, the quarterfinals of the Champions League, and has passed Madrid in the league.
15:30 ''We face the match with a lot of respect,'' Messi said. ''Madrid never plays poorly and when they appear to be struggling, they are even more dangerous. They have incredibly talented players, and we have to respect then more than ever.''
15:00 Regardless of the teams' contrasting form, one constant will remain: Lionel Messi and Cristiano Ronaldo will again vie to leave their mark on one of the most hotly contested rivalries in soccer.
14:30 Barcelona is on a run of 17 wins in its last 18 games and leads the league by one point, while Madrid is a shadow of the side that ended 2014 on a Spanish record 22-match winning streak that included a 3-1 win over the Catalan club.
14:00 A surging Barcelona has overhauled Real Madrid in the Spanish league standings, and the team now has the chance to open up a significant gap in the second ''clasico'' of the season on Sunday.
Venue: Nou Camp, Barcelona
Referee: Antonio Mateu
Barcelona: 1st with 65 points after 27 games.
