Barcelona striker Samuel Eto'o is considering a "stratospheric offer" that could make him the best paid player in the world, according to the Spanish club's president Joan Laporta.
Asked in a radio interview about interest from Premier League club Manchester City, Laporta said the Cameroon striker would find it hard to refuse an offer he also described as "enormous".
"He has a stratospheric offer from another club that would make him the best paid player in the world," Laporta told radio station iCat FM.
Laporta added: "It's becoming clear that he has an offer that's enormous. I believe he wants to stay and I'd like him to ... but an offer like this is very hard to turn down."
Barcelona are negotiating with Eto'o over a possible extension to his contract, which runs out next year.
Manchester City, owned by Abu Dhabi billionaire Sheikh Mansour bin Zayed al Nahyan, have already spent big money to sign Gareth Barry and Roque Santa Cruz for next season.
Barcelona are interested in Valencia forward David Villa while Laporta said a deal for the 20-year-old Keirrison of Palmeiras was close to being agreed.
