Real Madrid take on Barcelona this weekend in the first El Clasico of the season, with Luis Suarez making his eagerly awaited debut for Barcelona in the Spanish La Liga. The rivalry between the two clubs makes this the biggest game in world football, but even more eyes will be on the Bernabeu this weekend with the galaxy of stars coming up against each other in one of the most talked about El Clasico’s in the history of the fixture. Barcelona new boy Suarez is finally eligible to face Real at the Bernabeu after serving his four-month ban for biting Italy’s Giorgio Chiellini at the World Cup. Barcelona coach, Luis Enrique has confirmed the former Liverpool star will make his debut, and if he starts the match, he is likely to line up alongside Lionel Messi and Neymar for the first time in Barcelona’s deadly-looking front three. Messi is excited at the prospect of linking up with Uruguay star Suarez for the first time. “We are excited for Luis to play because he will add his strength to the team, I’m happy for him because he has spent a long time off the pitch,” said Messi. The game pits the two best players in the world against each other with Messi leading Barcelona and Cristiano Ronaldo the key man for Real. Messi could make yet more history on Saturday as he sits just one goal adrift of Telmo Zarra’s record of 251 goals in the Spanish top flight and achieving the record against bitter rivals Real would make it all the more special. Ronaldo, who has scored 15 goals in seven La Liga games this season, has played down talks that the match will be decided between himself and Messi. “It will be a difficult match because Barcelona are playing well, I’m not going to play against Messi, I’m going to play against Barcelona,’’ said Ronaldo.
