A review of the weekend's action so far in the Spanish Primera Division.
Atletico Madrid failed to reclaim second place from Real Madrid after they were held to a 1-1 draw by Valencia on a rain-soaked evening at the Vicente Calderon.
Jonas gave the visitors the lead on five minutes but Radamel Falcao levelled the score a minute later.
Valencia were superior in the first half but Diego Simeone's side improved in the second period and thought they should have been awarded a penalty for a handball by Jonas.
On Saturday, Lionel Messi again made history but his goal was not enough to earn Barcelona a win as they drew 2-2 with relegation-threatened Celta Vigo.
The Argentina international is no stranger to treading new ground and his 73rd-minute goal on Saturday night meant he has scored in 19 successive Primera Division matches.
In doing so he has found the net against every other side in the competition - the first player to ever do that in consecutive matches - and he has 29 goals from his last 19.
Saturday night's would not be the winner, though, with Borja Oubina's late header earning Celta a point, with Naxto Insa's opener having been earlier scrubbed out by Cristian Tello's goal.
Real Madrid missed the chance to make things slightly less comfortable for Barcelona at the top as they were held 1-1 by relegation-fighting Real Zaragoza at La Romareda.
Barcelona's draw meant second-placed Madrid could have trimmed their arch rivals' lead to 11 points if they could beat Zaragoza and claim a seventh successive league victory
However, like Barca, they had to settle for just a point with Rodri putting Zaragoza ahead early on before Cristiano Ronaldo levelled things up just before the break with his 28th La Liga goal of the campaign.
Neither side could go on to force a winner in the second half, with Marcelo hitting the post for Madrid and both goalkeepers making a number of vital interventions.
On Sunday, Osasuna's hopes of avoiding relegation were handed a huge boost after they came from behind to beat Valladolid 3-1.
An own goal by centre-back Ruben gave the hosts an early lead but two goals by Kike Sola within 10 minutes after half-time put Jose Mendilibar's side in the lead, before Miguel De Las Cuevas scored his first goal for the club to make sure of the points.
Real Sociedad's push for a top-four finish suffered a slight setback as they were held to a 2-2 draw at Espanyol.
While victory would have been a significant boost to their Champions League aspirations, they may have left the Cornella-El Prat thankful for a point as Javi Lopez's own-goal 14 minutes from time denied the hosts maximum points.
It was the second time Sociedad had come from behind in the match, David Zurutuza scoring either side of strikes from Sergio Garcia and Christian Stuani in a busy first half.
Deportivo La Coruna recorded back-to-back victories for the first time this season after a narrow 3-2 win over relegation rivals Real Mallorca.
Victor Casadesus gave Gregorio Manzano's side the lead but a wonderful goal from Silvio put Deportivo back on level terms. Carlos Marchena gave the visitors the lead early in the second half and Riki extended their advantage, before Alfaro scored a late goal to set up a tense finish.
Back to Saturday's action and Malaga claimed a 3-1 victory at Rayo Vallecano.
Weligton gave Manuel Pellegrini's side the lead but Piti levelled for the hosts from the penalty spot.
Former Real Madrid forward Julio Baptista scored his first goal in 18 months to restore Malaga's lead early in the second half before Pedro Morales secured all three points with a wonderful goal.
A strike by Ruben Garcia was enough to give Levante to their first victory since January 26 as they beat Sevilla 1-0.
Ruben struck five minutes before half-time and although the visitors rallied late on they could not force an equaliser as Levante picked up their first win since beating Valladolid.
