Barcelona defender Gerard Pique has called for more signings this summer.

Pique made the claim when asked about new arrival Frenkie de Jong from Ajax.

"De Jong? The club has to look for players who can perform and help us win trophies," said Pique.

"De Jong has shown that he has the level to compete with the best."

Pique also spoke of Barca's Champions League collapse to Liverpool.

"It was one of my worst experiences as a professional [footballer]," he added.

"We try to play Barcelona's style [of play]; sometimes it's easier to do, sometimes it's more difficult.

"It's not just what we want to do; sometimes the other team plays.

"There are times where it's not possible to have the ball and control the game."
