Roberto Carlos Feels Barca Threat

Real Madrid defender Roberto Carlos feels Barcelona may be the biggest threat to the Merengues' defence of the Liga title.

"Barcelona are finally looking like they can be our biggest rival," he told Radio Marca.

"They have had four years of winning nothing and I must admit we lose a lot when they are not strong."

"I have seen how they have improved things. I think they can challenge us, along with Real Sociedad, Depor and Valencia."
