Barcelona captain Sergi Busquets hailed the impact of Pierre-Emerick Aubameyang after victory at Valencia.

Former Arsenal captain Aubameyang struck a hat-trick for the 4-1 win.

Busquets said, "In the first half we were very effective, and this allowed us to dominate the game and play calmly. It was a game well played, in general.

"We had done well also other times, but with less effectiveness."

"He has been working very well, since the first day," Busquets said of Aubameyang. "He came from a period of inactivity, but it is already the second game he plays as a starter and we hope he can continue to help us in this way.

"He is a great player, it's a luxury to have him on the team."
