Barcelona defender Jeremy Mathieu has insisted that he has no problem filling in at full-back for the Catalan outfit this season.

The Frenchman, who was signed from Valencia this summer, started the season at centre-back for Barca, but was switched to left-back for Saturday's 2-0 win over Rayo Vallecano.

"I hadn't been playing there but I had a good feeling," he told Marca.

"The coach asked me to work at left-back and to go there. It wasn't new to me. I know the position well. I think I did well in attack, contributing when possible.

"And we're still not conceding goals in the league."

Barcelona have still not conceded a single goal in the league this season.
