The Cameroonian striker—drafted in by Jose Mourinho to add attacking firepower during the 2013-14 season—is the subject of interest from across the globe, reported by the Metro:
Eto'o has received offers from MLS and Australian teams, along with several Italian and Spanish sides – including his old outfit Real Mallorca.
However, Spurs believe they could tempt the striker to remain in London, where he has settled and fallen in love with the Premier League.
Spurs, like Chelsea, suffered under their forwards' lack of output last season. Emmanuel Adebayor was the only out-and-out striker to net more than 10 goals from either club during the Premier League campaign that has just ended, with Eto'o offering the next best total at nine, per WhoScored.com.
Eto'o is no longer the lightening-quick goalscorer who lit up La Liga and Serie A, but he offers an assured sense of experience when needed. The 33-year-old scored vital goals against Liverpool, Manchester United and Galatasaray, prolonging Chelsea's title hopes into the final weeks of the season.
He remains an adept finisher, the type of player who can pop up with a much-needed strike, something Roberto Soldado didn't offer during his debut campaign with Spurs.
Mourinho, who was famously caught mocking Eto'o's age in a secretly filmed exchange published by Canal+, may have to replace his former Inter Milan colleague. Eto'o recently called the manager a "puppet" when discussing the jibe, indicating a further breakdown in the pair's relationship, reported by the Confederation of African Football website via John Drayton of the Daily Mail.
Perhaps ironically, it was Eto'o's goal against Spurs which prompted his now-famous "bad back" celebration in response to Mourinho.
Chelsea remain conscious of UEFA's financial fair play rules, suggesting they may happily remove Eto'o from the wage bill in order to land new talent.
Eliaquim Mangala recently confirmed he would opt to join the Blues over Manchester City "because it is London," per Jamie Jackson of the Guardian.
Such a comment could lure Mourinho into acting, especially considering he has already secured Kurt Zouma's signature. Alongside Mangala, Zouma ranks among Europe's top young defenders and has the potential to be a future juggernaut, so their potential development together is sure to be an attractive prospect for Chelsea fans.
James Cooper of Sky Sports believes Mangala is "at the top" of City's wishlist, suggesting Chelsea may face a battle for his signature.
The Blues are said to have agreed a deal with Atletico Madrid hero Diego Costa, plugging any gap potentially left by Eto'o without hesitation, per Sky Sports. Mourinho may prefer to see Fernando Torres or Demba Ba leave over the African striker, who wouldn't land Chelsea a transfer fee due to his imminent contract expiry date.
With his deal set to end in "just a few weeks," per Metro, we can expect Eto'o's future to be wrapped up soon. He may receive the opportunity to flaunt his skills at the summer's World Cup, an occurrence that could see many more clubs throw offers his way.
