Messi hat-trick steers Barca to unbeaten 35-game record
Lionel Messi scored a hat trick as Barcelona defeated nine-man Rayo Vallecano 5-1 to become the first Spanish club to play 35 consecutive matches without a loss, breaking Real Madrid's record of nearly three decades ago.
Two goals in as many minutes midway through the first-half killed the game as a contest as Ivan Rakitic and Messi netted before Diego Llorente saw a straight red card for a high challenge on Rakitic.
Messi completed his hat-trick either side of Manucho's consolation for Rayo. Luis Suarez also missed a penalty after Manuel Iturra was also sent-off for the hosts before Arda Turan rounded off the scoring with his first Barca goal.
Barca now lead Atletico Madrid by eight points with Real Madrid a further four points adrift in third with 11 games remaining.
Despite Rayo's precarious position just above the relegation zone, Barca boss Luis Enrique showed the Madrid side plenty of respect by naming his strongest side bar at fullback where Jeremy Mathieu and Sergi Roberto replaced Jordi Alba and the suspended Dani Alves. Rayo were unbeaten in their seven league games themselves and forced Barca 'keeper Claudio Bravo into a smart early save as the Chilean international flew to his right to turn away Adrian Embarba's drive.
However, Rayo's high defensive line was offering plenty of encouragement to the European champions and it seemed only a matter of time before Barca took advantage as Carlos made a good save at his near post to deny Messi.
