DHAKA: Barcelona restored their four-point lead at the top of La Liga with a tense victory over Celta Vigo, who ended with 10 men in bizarre circumstances.
It took 73 minutes for the breakthrough - Jeremy Mathieu scoring the only goal with a back-post diving header from Xavi's free-kick.
Celta had Fabian Orellana sent off for throwing some grass at Sergio Busquets as he was getting ready to take a free-kick.
Lionel Messi chipped over late on.
Despite the significance of the result, the game might be better remembered for Orellana's dismissal with two minutes left.
The Chilean, frustrated with how long Busquets was spending to take his free-kick, picked a lump of grass off the ground and threw it in the face of the Spain international, who held his face and started to go down.
Real Madrid had closed the gap with a 9-1 demolition of Granada in the early kick-off, with Cristiano Ronaldo scoring five goals for the first time in his career.
