Barcelona gave stand-in coach Jordi Roura a winning start as goals from Xavi, Lionel Messi and Cristian Tello downed Real Valladolid 3-1 to re-establish a nine-point lead at the Primera Division summit
Roura is deputising for Tito Vilanova, who was discharged from hospital last night after undergoing an operation on his parotid gland on Thursday, and saw his side take a 1-0 interval lead when Xavi tapped in Jordi Alba's cross.
The Spain midfielder then set up Messi for his 91st and last goal of an extraordinary 2012 and, after Javi Guerra pulled one back, Tello rounded off the win in injury time.
"We wanted to dedicate the win to Tito.," Xavi said afterwards.
"He's not going through the best of times but now he's home, and that's great news. The operation went well and we worked hard to be able to dedicate this victory to him.
"We're on a great run and we want to continue on this path. We're physically strong and when we return from the break we want to continue in this form."
Jose Mourinho remained defiant last night after watching Real Madrid's fading title hopes hit with another blow as his side slumped to a 3-2 defeat at Malaga.
Roque Santa Cruz struck twice in three second-half minutes to help fourth-placed Malaga heap the pressure on Madrid coach Jose Mourinho, who omitted captain Iker Casillas from his starting line-up.
Isco put Malaga ahead in the 48th minute before an own goal from Sergio Sanchez drew Madrid level midway through the second half.
But substitute Santa Cruz, who had been on the pitch less than 10 minutes, stunned the visitors by putting Malaga 3-1 ahead with a double strike in the 73rd and 76th minutes.
Benzema pulled another goal back with eight minutes remaining but Madrid could not find an equaliser.
The result leaves Real 16 points behind Barcelona, but Mourinho insisted he had no intention of stepping down despite the poor run of form from the Bernabeu side.
"Neither before, during or after the game have I thought about resigning," he said.
"I don't fear for my position. This is football. I'm not a child, nor have I been here for a couple of days.
"Coaches know that football has no memory and only takes into account what was done today and not what was done yesterday."
Apono and Helder Postiga were on target as Real Zaragoza ran out impressive 2-0 winners at Athletic Bilbao.
Zaragoza had won just one of their last five going into the game but looked in fine form as they eased to the three points courtesy of Apono's penalty and Postiga's effort shortly before the interval.
Real Mallorca got their first win in 15 games in all competitions as they came from behind to beat Champions League-chasing Real Betis 2-1 at the Benito Villamarin.
Benat's free kick had given the hosts an early lead, but Victor brought the Islanders level with a fine header on the half-hour mark.
And the comeback was completed just two minutes into the second half when Mario's challenge on Victor was deemed to have taken place inside the area and Javi Marquez comfortably slotted home the resultant penalty.
Granada secured only their second win in seven league games with a deserved 2-1 victory over Osasuna.
Nino had fired the hosts into an early lead with a looping header from Raoul Loe's flick-on, but Granada dominated thereafter and should have been level well before Diego Mainz did find the back of the net from Dani Benitez's free kick four minutes before half-time.
Benitez himself then put his side ahead two minutes into the second period with a wonderful left-footed strike.
Lyon moved level on points with Ligue 1 leaders Paris St Germain after a comfortable 3-0 win over Nice at the Stade de Gerland.
Goals from Lisandro Lopez and Anthony Reveillere either side of half-time put the title hopefuls on course for victory while Bafetimbi Gomis' penalty sealed a comfortable victory.
It was an unhappy return to Lyon for former boss Claude Puel whose side ended the match with 10 men after David Ospina was sent off in the build-up to the Gomis spot-kick.
Lyon's Dejan Lovren saw red after picking up a second yellow late on in what was the only negative of the night for Remi Garde's men.
Rennes go into the forthcoming two-week winter break in the top four following a 4-2 triumph at Ajaccio in a match which was delayed by 10 minutes after their fourth goal sparked a pitch invasion.
Julien Feret struck from an indirect free kick in the penalty area after goalkeeper Guillermo Ochoa handled Carl Medjani's back-pass but a section of Ajaccio supporters, angered by the taking of the free kick, stormed from the stand to protest, forcing referee Ruddy Buquet to suspend the game until order was restored.
Rennes had twice come from behind in the first half, Feret and Romain Alessandrini equalising after goals from Adrian Mutu and Fousseni Diawara. Cheick Diarra put them ahead for the first time before Feret's controversial clincher.
Bastia won by the same score line, with three goals in the opening half-hour proving decisive against rock-bottom Nancy.
Jerome Rothen, Anthony Modeste and Sambou Yatabare were all on the scoresheet in the early stages before Benjamin Moukandjo clawed one back for the visitors.

Bordeaux's goalless stalemate with Troyes, who are six points adrift of safety, was their fifth draw in succession.

Mathias Jorgensen further extended PSV's advantage in the 37th minute before second-half goals from Luciano Narsingh and his replacement Jurgen Locadia sealed the victory.
Vitesse Arnhem missed the chance to replace Ajax in the top three ahead of the champions' match with FC Utrecht as they were beaten 2-1 at Heerenveen.

Seventh-placed NEC Nijmegen are also going through a bad patch and their winless run stretched to four matches after they fell to a 2-0 defeat at ADO Den Haag.

The victory leaves pacesetters Celtic seven points clear of Inverness, who climbed back into second place with a 4-1 home win over Dundee.
Billy McKay continued his rich goal scoring streak with a double, netting the opener from the penalty spot before taking advantage of some slack play from the visitors to put Caley Thistle 3-1 up just after the break and take his tally for the season to 18 goals.
The striker has now found the net in seven consecutive matches, with seven goals in his last three games, topping the SPL scoring charts with 15 league strikes.
Caley Thistle's other goals came from Owain Tudur Jones and Andrew Shinnie with Dundee's reply coming from Nicky Riley, who had briefly made it 1-1 in the first half.
Niall McGinn's second-half double earned Aberdeen a 2-0 win over St Johnstone at a storm-lashed Pittodrie.
Lazio are the closest challengers to Serie A leaders Juventus after they moved up into second with a hard-fought 1-0 triumph at Sampdoria.

The Biancocelesti are now eight points behind pacesetters Juventus, who beat Catania 3-1 last night, at the beginning of the winter break.
Inter lost further ground on their rivals although they were grateful for a point in the end as Esteban Cambiasso's strike five minutes from time cancelled out Ciro Immobile's 77th-minute effort for Genoa.

Andrea Stramaccioni's men were also leapfrogged on goal difference by Fiorentina, who finished the year in the Champions League places with a comfortable 3-0 victory at lowly Palermo.
Stevan Jovetic had been a doubt for the game due to a thigh injury but opened the scoring in the 50th minute and then doubled his side's lead with a penalty seven minutes from time.
Jovetic might have been celebrating a hat-trick in the final minute after Fiorentina had won another penalty, but centre-back Gonzalo Rodriguez took over spot-kick duties and confidently converted.
Two late goals saw Napoli end a chastening week with a flourish following a 2-0 triumph at 10-man Siena.
