LaLiga president Javier Tebas has questioned Barcelona's transfer plans.
While Real Madrid have spent big this summer on a raft of additions, Tebas doubts Barca can do the same regarding PSG star Neymar and Atletico Madrid's Antoine Griezmann.
He insists Barca would have to first sell to fit into financial fair play demands.
"Can they afford to have them both on the same team? It depends on who they sell, I do not have the numbers here and I could be wrong," said Tebas.
The LaLiga supremo also commented on Benfica starlet Joao Felix's potential move to Atletico Madrid.
He added: "Any player who is great is welcome to Spanish football."
