Barcelona coach Ernesto Valverde admits he's been totally surprised by the impact of Ansu Fati.

Fati, 16, scored a goal and assisted another one in Barcelona's 5-2 win over Valencia.

"Becoming a Barcelona player is not straightforward," Valverde said at his post-match press conference.

"He is focused and good.

"It is not normal to score with the first touch, to give an assist with the second and to almost score with the third.

"We are interested in getting him to know this level and for him to see the pace of the work, so that he can contributes more to us."

Fati, along with Carles Perez, were two La Masia products who got their chance to play with the seniors following Barcelona's issues with the injuries.

"Throughout a season there are always spaces for players to appear," he added.

"When they appear they have to do well, because it is their moment.

"Fati did very well when he was at the Barcelona B team.

"It is clear that doing well in those moments is important.

"Both players are taking advantage of it."
