Barcelona and Real Madrid were both held to draws in La Liga on Saturday, while Malaga reclaimed fourth spot provisionally.
Lionel Messi's goal against Celta Vigo in their 2-2 draw means that the Barcelona star has now found the net against each opponent in the league this season.
The Argentina international beat Celta goalkeeper Javi Varas from close range in the 73rd minute after being set up by Cristian Tello to make it 2-1, and take his season's league tally to 43.
Messi's goal was not enough for the full three points, though, as Borja Oubina restored parity in the closing stages of the encounter.
Messi's goal also saw him extend his scoring streak to an incredible 19 consecutive matches in the Spanish top flight.
Despite the draw, Barcelona's still hold a 14-point lead at the top of the table following Madrid's lacklustre 1-1 stalemate at Real Zaragoza.
On-loan Barcelona B player Rodri gave the hosts the perfect start on six minutes as Jose Mourinho's men struggled to get a foothold in the game.
Cristiano Ronaldo managed to net an equaliser before the break with his 28th league strike of the season, but they could not find the winner in a disappointing second half.
Elsewhere on Saturday, Malaga ended a four-game winless run with a 3-1 win over Rayo Vallecano.
Malaga had failed to pick up points against Real Betis, Atletico Madrid, Real Valladolid and Espanyol in recent weeks but goals from Weligton, Julio Baptista and Pedro Morales saw this season's surprise-packets return to winning ways.
