Former PSG chief Patrick Kluivert has no doubts over Marco Verratti's quality.

Verratti is a big money target for Barcelona this summer.

Ex-Barca striker Kluivert said: "He is worth more than 100m euros and the president isn't going to let him go.

"I can't be 100 percent sure, but it will be very difficult.

"I know the player wants to go [to Barcelona], but PSG is the boss."
