Real Madrid defender Sergio Ramos admits they must beat the best when they face Barcelona star Lionel Messi this weekend. Messi struck all four goals in Barcelona' 4-1 win over Arsenal last night to warm up for the El Clasico.

Ramos conceded: "Facing Messi you are facing the best, not only now, he's been like this for a few years. We must take our hat off to him because he is a player that makes the difference, and today, although Barcelona has its bad games or good games Messi continues to maintain that difference, and at a high level.

"He is the most feared player of Barcelona."

He added: "We face a moment in the season where points really make the difference between Barcelona and us. Any error can cost you the league."
