Ronald Koeman was sacked last October and replaced by Xavi as the manager.
The former Barca boss has now questioned the motive behind Messi’s move to PSG last summer.
Lionel Messi left Camp Nou last summer as the club was unable to renew Messi’s contract due to financial regulations imposed by La Liga.
In return, they signed free agents like Sergio Aguero, Eric Garcia and Memphis Depay in that summer window.
The club invested heavily in the January transfer window with key players such as Pierre-Emerick Aubameyang, Dani Alves, Adama Traore and Ferran Torres joining the Catalan giants.
This heavy investment has led to Koeman suggesting that the club had any ulterior motive behind Lionel Messi departure.
Koeman told Dutch newspaper Algemeen Dagblad: “It was at the insistence of the club’s management that I agreed to the departure of some players to put the finances in order.
“But then when you see that they go and sign a player for €55million (Torres) shortly after letting Lionel Messi go…
“Then you wonder if there wasn’t something else going on.
“Why did Messi have to leave?”
