Barcelona chief Robert Fernandez admits they want more from Paco Alcacer.

The striker is yet to score since joining from Valencia.

"The famous fourth forward, he could help us more, he knows he has to wait for his moment," said Robert.

"I always told him that to play at Barca is very difficult but you have to be prepared. In front of him is the best centre-forward in the world, Suarez. He's scored many goals in the top flight, I'm convinced that he will accomplish the objective of helping the team, whether he starts or not."
