Barcelona coach Tito Vilanova has admitted that winning against Osasuna away from home on Sunday is not going to be easy.

The Catalan giants travel to Pamplona for their first away game of the 2012-13 La Liga campaign.

"Pamplona is always a complicated place to go and win, with the atmosphere the crowd creates and the also the way [Jose Luis] Mendilibar sets his teams out," said Vilanova on Saturday.

"They are brave and they go out and chase you down high up the pitch.

"Osasuna players are well suited to that style of play and there are always a lot of corners and free kicks that they know how to take advantage of."

Barcelona began the new league season with a comfortable 5-1 victory over Real Sociedad at Camp Nou last weekend.
