MADRID, Dec. 16 (Xinhua) -- Leo Messi underlined his status as the greatest goalscorer in history as his 89th and 90th goals of 2012 helped his side to a 4-1 win at home to Atletico Madrid on Sunday night.

Atletico Madrid took the lead early in the game through a fine Radamel Falcao goal and for a while his side were in control and it looked as if he could win the 'battle of the goalscorers' against Messi.
However, Adriano Correira equalized with a magnificent left foot shot and Sergio Busquets kept calm to net from close range to turn things around for Barca before the break and the second half was all Barca, allowing Messi to confirm his status the best striker in Spain and probably the world.
Real Madrid's title challenge appears to have died as a result of a 2-2 draw at home to lowly Espanyol.
An 89th minute goal from Juan Albin gave Espanyol the draw and stun Real Madrid, who had come back from behind thanks to goals from Cristiano Ronaldo and Fabio Coentrao had cancelled out Sergio Garcia's opener for the visitors, who remain second from bottom of the table with just 12 points from 16 games.
