(CNN) -- Samuel Eto'o looks set to snub Manchester City's "stratospheric" offer that could make him world football's top-paid player, the Cameroon striker's agent warned on Monday
Top scorer Samuel Eto'o helped Barcelona to win an unprecedented treble last season.
Barcelona president Joan Laporta confirmed City's interest on Sunday, saying Eto'o will will find it hard to turn down such a huge pay package, despite being in negotiations over a new contract at the Nou Camp.
However, it seems 28-year-old Eto'o is unhappy at being forced out of Barcelona, where he has one season of his present contract left to run.
And, rather than accept the riches on offer at City, he is preparing to see out the final year of his contract before leaving Barcelona for nothing next summer.
"If there is not a 180-degree turnaround then he will stay with Barcelona," Eto'o's agent Josep Maria Mesalles told Spain's ONA FM radio station.
The news will undoubtedly come as a blow to City boss Mark Hughes, who is due to return from a family holiday on Tuesday.
Having missed out on Kaka last January, it would continue to prove City will struggle to attract the marquee signing their Abu Dhabi-based backers have been looking for without the added lure of Champions League football.
Even the long-touted capture of Carlos Tevez will not be taken for granted until the Argentina star has signed on the dotted line at some point after July 1.
Eto'o has previously said that a move to City did not interest him, but the club's billionaire owner Sheikh Mansour Bin Zayed Al Nahyan is determined to finance a deal for the player, who scored 36 goals in Barca's treble-winning season.Who are the world's most wanted footballers?
"Eto'o has a stratospheric offer from City, which would convert him into the best paid player in the world," Laporta had told Catalan radio station iCat FM on Sunda.
"It's starting to become clear that he has this monster offer. He wants to stay but an offer like this is very difficult to refuse.
"If Eto'o accepts this stratospheric offer we will have to bring in someone."
Hughes has already brought in England midfielder Gareth Barry in a $20 million deal and signed Paraguay striker Roque Santa Cruz from Blackburn for a reported $30 million.
The Eastlands outfit are also expected to sign Tevez from city rivals Manchester United after the Argentina forward decided not to accept a new contract with the Premier League champions.
United had agreed to pay the required $42 million to make Tevez's loan deal permanent, and also offered the player a five-year contract, but he opted to leave Old Trafford, saying he did not feel wanted by the club.
City hope that Eto'o and Tevez will link up with Brazil star Robinho, who was lured to Manchester from Real Madrid last August in a $58 million deal when he had appeared set to join Chelsea.
Eto'o has scored 125 goals in 184 games for Barcelona since joining from bitter rivals Real Madrid for €24 million (now worth $33.7 million) in 2004, having been on loan with Mallorca for the previous two seasons.
