LaLiga president Javier Tebas admits he struggles to see how Barcelona can sign Lionel Messi.

The PSG star remains a target for Barca, though a return faces the obstacle of LaLiga's Financial Fair Play.

Tebas said on RMC: "As of today, I see it as complicated. There is still time, but there will have to be an exit of players and a reduction in the wage bill.

"There will have to be in order to be able to register Messi. And then there is one thing we don't know, which is Messi's salary. There are still many variables.

"Barça is not like PSG, who have a tap of gas and money to have a large wage bill. It has to reduce the wage bill to be able to sign players.

"It's like the metro, let people out so they can come in. And people still have to get out of the metro."
