Alex Song has revealed the importance of Tito Vilanova's advice to him before he made his Barcelona debut in the club's 1-0 win over Valencia at the weekend.

The Cameroon midfielder, who joined Barcelona from Arsenal during the summer, has acknowledged that Vilanova played a pivotal part in his performance on Sunday.

The 24-year-old told Sport: "The coach spoke with me ahead of the game and explained what he expected of me.

"That really helped me calm down a bit and gave me a lot of confidence. My teammates also talked to me a lot and that was very helpful."

Barcelona's victory over Valencia ensured that they maintained their 100% start to the La Liga season.
