Barcelona have crowned their title triumph with a comeback win at Atletico Madrid.
Barca were confirmed as champions on Saturday night when Real Madrid could only draw at Espanyol, but initially looked set to mark the occasion with defeat as they trailed to Radamel Falcao's opener when Messi limped off on 67 minutes.
But by the time their talisman had reappeared, changed and showered, on the touchline Barca had snatched away victory.
Alexis Sanchez equalised on 72 minutes, following a one-two with Cesc Fabregas, before Gabi awkwardly turned a David Villa shot into his own net nine minutes from the end.
The final whistle drew some title celebrations from the Barca players in front of the travelling support at the Vicente Calderon.
