Madrid - The big football game in Spain this weekend sees runaway leaders Barcelona at home to rugged Valencia on Saturday.
Barca are four points above second-placed Villarreal in La Liga, with Valencia five points behind them in third place.
Valencia will make the trip to the Camp Nou - where they were thrashed 6-0 last season - without captain Carlos Marchena who was sent off in last Sunday's 3-2 defeat of Betis.
In addition, Brazilian midfielder Edu and Spain striker David Silva are injured.
"It's going to be a difficult game for us," said old Valencia warhorse Ruben Baraja.
"But we have got fairly good results there in the past few years, and I think we can do this again on Saturday."
