However, those bids have been rejected with PSG holding out for more money.
“The player is happy to reduce his wages from 38 million euros net to 23 million euros net,” said Balague.
“It is an interesting situation at Barcelona. They feel they have to try really hard to get him back.
“Lionel Messi, Gerard Pique and Luis Suarez want him back but also the president Josep Maria Bartomeu has two more years in his mandate and he wants to leave a big legacy. Can you imagine all those players that have been mentioned and Neymar as well?”
Valverde lamented the fact the transfer window does not close until 2 September and insisted he was “very happy with the squad”.
“It’s inconvenient and it’s not logical,” he said about the transfer window.
“The normal thing would be that the team you start with is the same one that will compete for the whole season.
“Now we have two weeks until the transfer window shuts and you can’t breathe easily until then. I’m very happy with the squad I have at the moment but I don’t know what will happen next.
Messi to miss season opener
Messi scored 51 goals in 50 appearances for Barcelona in all competitions in 2018-19 but will miss the start of this season because of a calf injury.
The Argentina international has not trained ahead of Friday’s game at San Mames and Valverde said: “We are not going to take risks with any player, even less with Leo.
“He hasn’t trained or played with the team. We will wait a while but his recovery process is going well.”
Friday’s game will be broadcast on ITV after the broadcaster agreed a continuation of their La Liga partnership to screen the Spanish top flight on terrestrial TV this season.
