|Barcelona travel to Rayo Vallecano looking to maintain their eight-point lead
"Vallecas is never an easy ground to visit and on Saturday they won’t just sit back and wait – they’ll go toe to toe with us."
The Barca coach then revealed he has been satisfied with his side's performances so far as the Catalans sit atop of the table with 22 points from eight games.
"I am very happy with the players’ performances and I have no complaints. Winning titles is important, but it’s maybe even more so to have the confidence that the players will be in the [title race] till the end of the season."
Saturday's match against Rayo is scheduled to kick off at 22:00CET.
