Lionel Messi netted two goals within 15 minutes of coming on as a substitute to give Barcelona a 4-2 comeback win over Real Betis on Sunday and push his team to the brink of the Spanish league title.
After his teammates had rallied back twice to level at 2-2, Messi went on in the 56th and four minutes later curled in a free kick to extend his scoring streak to 21 straight league appearances.
The Argentina forward struck again in the 71st by polishing off a superb passing combination with Andres Iniesta and fellow goalscorer Alexis Sanchez.
Barcelona leads by 11 points with four rounds to go and would clinch its 22nd domestic crown if defending champion Real Madrid drops points against Malaga on Wednesday.
Messi has been hampered for the past month by a right hamstring injury.
