Sergi Busuets hailed the performance of Leo Messi for Barcelona's victory over Celta Vigo.

The Argentine star scored a hat-trick in the Blaugrana's 4-1 win over Celta Vigo on Saturday, including two goals from freekicks.

"We have a very big advantage, he's the best in the world and also the best freekick taker in the world," Busquets told Movistar about Messi.

"He's been improving bit by bit and it was difficult.

"Having him is a very big advantage."

Busquets scored a rare goal to round off Barcelona's victory at the Camp Nou as they regained top spot in LaLiga Santander.

"I hadn't scored in a while, although that's normal," he said.

"The important thing was that the team won. We were struggling in LaLiga Santander and the Champions League and it was important to stay top and go into the international break with calmness."
