Samuel Eto'o led Barcelona to only their second away win of the season in a 3-0 victory over Valencia in the Primera Liga on Saturday.
The home side had no answer to the Cameroon striker's pace and power as he netted twice in the first half, proving he has fully recovered from the surgery that kept him sidelined for the first three months of the season.
Eidur Gudjohnsen added the third in the second period. For Valencia coach Ronald Koeman it was his side's sixth game in all competitions without a goal.
Second-placed Barca moved on to 34 points, one behind leaders Real Madrid who host Osasuna at the Bernabeu on Sunday.
Earlier, Espanyol climbed to fourth with an uninspiring 1-0 home victory over bottom club Levante. Defender Daniel Jarque stabbed the ball home from close range after nine minutes as last season's UEFA Cup finalists stretched their unbeaten run to 12 matches.
Espanyol joined third-placed Atletico Madrid on 30 points. Atletico visit Recreativo Huelva on Sunday.
Rijkaard left Ronaldinho on the bench and he was able to watch his team-mates tear into Valencia from the opening minute.

Portsmouth could have gone fourth but fell to seventh after losing 1-0 to Tottenham Hotspur at Fratton Park.
They remain on 30 points, behind Liverpool and Everton -- who won 2-0 at West Ham United -- on goal difference.
Arsenal have 37 points from 16 games to United's 36, with Chelsea on 34 and City on 33.
City, the only club in the top flight to have won all nine of their home league games this season, went ahead through Rolando Bianchi's seventh minute tap-in.
El Hadji Diouf equalised with a left-footed shot in the 31st and Kevin Nolan made it 2-1 to Bolton five minutes before halftime.
A Lubomir Michalik own-goal put Sven-Goran Eriksson's side back into the game three minutes after the break and Darius Vassell slotted in a third in the 77th before Kelvin Etuhu grabbed the fourth in stoppage time.
Struggling Wigan Athletic were the day's top scorers, beating 10-man Blackburn Rovers 5-3 at the JJB Stadium after squandering an early 3-0 lead.
