Benfica are struggling to find an agreement with Atletico Madrid over Jose Antonio Reyes.
A Bola says Benfica are running out of funds to sign the Spaniard after deals for Real Madrid striker Javier Saviola and River Plate's Radamel Falcao.
Reyes may be forced to start preseason training with Atletico, though Everton have been linked with the ex-Arsenal man.
