Two goals against the Aragonese strugglers brings up yet another landmark for the irrepressible Rosario native, and puts him within touching distance of Muller's recordBarcelona's Argentine phenomenon Lionel Messi, as his two goals against Real Zaragoza took him to 60 for the 2011-12 season in all competitions.
The 24-year-old forward was on target for the Liga and Champions League holders 39 minutes into their match against the Aragonese side, who had taken the lead in the first half thanks to Carlos Aranda's effort.
Messi struck from 15 yards out after receiving the ball from Alexis Sanchez to record his first of the match, putting Barca 2-1 up three minutes after Carles Puyol had levelled proceedings.
The second came from the penalty spot, as the Argentine calmly stroked the ball home with five minutes remaining to make it 3-1 for the Catalan giants.
The star's 60th goal puts him just seven behind Gerd Muller's all-time record for a single European season.
The German idol netted 67 times for Bayern Munich in the 1972-73 campaign. Lio's goals include 38 in La Liga; two in the Copa del Rey; three Supercopa strikes; one in the Uefa Super Cup; two in the Club World Cup and a further 14 in the Champions league.
