Palermo president Maurizio Zamparini has said Arsenal, Barcelona, Chelsea, Manchester City and Paris Saint-Germain are possible destinations for in-demand Paulo Dybala and Franco Vazquez.
The striker and the midfielder are both expected to leave the Serie A club at the end of the season, with Zamparini admitting Palermo are unlikely to keep either.
But he has already insisted that neither would be sold on the cheap, warning that Argentinian striker Dybala would cost at least €40 million, with Vazquez reportedly valued at €20m.
The president named five of Europe's wealthiest clubs as their main suitors, but ruled out the prospect of either joining AC Milan.
"Dybala and Vazquez will probably be sold this summer," he told Pianeta Milan.
"Will they go to Milan? No, they certainly won't be joining the Rossoneri. They are being tracked by Juventus, Arsenal, Barcelona, Manchester City, Chelsea and Paris Saint-Germain."
Zamparini had claimed in January that Manchester United had shown an interest in Dybala, a 2012 signing from Instituto de Cordoba.
The striker has scored 12 goals in Serie A this season, and his club president has previously compared him to City top scorer Sergio Aguero.
Vazquez, also born in Argentina, has been called up by Italy and signed a new contract as recently as January.
