Barcelona coach Xavi admits they weren't at their best for Tuesday's win against Celta Vigo.

Memphis Depay gave Barcelona the lead and Pierre-Emerick Aubameyang completed a brace to lead the Blaugrana to a convincing 3-1 LaLiga Santander win over Celta Vigo at the Camp Nou on Tuesday.

Ousmane Dembele produced an extraordinary individual move on the half an hour mark, when he went past a couple of Celta players before teeing up Memphis, who opened the scoring for the hosts.

Marc-Andre Ter Stegen made a solid save to deny Thiago Galhardo six minutes later and Barcelona doubled their lead through Aubameyang before the break.

The Blaugrana converted their first chance in the second half into a goal through the former Arsenal striker, with Dembele registering yet another assist.

Celta bounced back instantly and pulled one back through Aspas, but Jeison Murillo received a straight red card after bringing down Memphis outside Celta's box.

Then, Ronald Araujo made way for Clement Lenglet as he had to be taken to the hospital after a head collision with teammate Gavi.

Riqui Puig, who came off the bench at half time to replace Ferran Torres, scored one of his own, but his goal was ruled out for offside.

Xavi later said: "Honestly it was not a good game, we didn't play well. After the red card we played well, we had passion, but 11 vs 11 we suffered.

“It's a very important win, especially when you don't play well. At least we competed. We need to keep going, this is not the way but at least we won."
