Lionel Messi tees up victory as Barcelona cling on to fading title hopes

Messi teed up Arturo Vidal's winner at Jose Zorilla to become the first player to provide 20 assists in Spain's top flight since Xavi Hernandez in 2009.

Victory for Barça means Real Madrid cannot clinch the title on Monday by beating Granada but only an incredible collapse will prevent them putting their name on the trophy later in the week.

If they beat Granada, Madrid will win La Liga by prevailing at home to Villarreal, regardless of Barcelona's results. Overall, Madrid need only five points from their remaining three matches to secure their third La Liga title in eight years.

"We are doing things that deserve more than where we are," said Barca coach Quique Setien.

"To win La Liga, I don't know, because our rival is winning everything." Yet even as Barca's turbulent domestic campaign draws to a close, Messi continues to shine.
