The president of the Spanish Football League, Javier Tebas, believes many of the most talented players in Spain will leave the country in the next four years as clubs are forced to pay off their debts.
Spain international Jesus Navas is expected to sign for Manchester City from Sevilla and, with Radamel Falcao already heading for Monaco from Atletico Madrid, Malaga midfielder Isco could also leave Spain.
The future of the two highest Spanish scorers in the Primera Division last season, Alvaro Negredo and Roberto Soldado, remains uncertain.
In an interview with AS, Tebas said fans should expect more players to leave the league, stressing the only way for teams to compete with Real Madrid and Barcelona was to resolve their financial troubles.
He said: "Fans need to be aware that there is going to be an exodus of players over the next three to four years, because we need clubs to decrease their debts if they are able to become alternatives to the big clubs."
Tebas also reiterated his support for a model of Financial Fair Play for Spanish football, declaring: "The fundamental idea, with a few caveats, is that clubs must spend what they earn."
The president added that the league was looking to expand its global audience, and said this would have an effect on how it scheduled games in the future.
"We need to look to the foreign market if we are to increase our television revenues, and that means we have to pay attention to the television operators abroad, and make things easier for them in terms of kick off times," he said.
