The striker has had an argument with his new manager Sinisa Mihajlovic.
However, the Cameroonian is already in trouble at his new club, according to a report on Sky Sports.
The former Barcelona and Inter Milan striker has found himself in hot water with the volatile Sampdoria manager Sinisa Mihajlovic.
Eto'o made his debut for Sampdoria at the weekend, but they were thumped by Torino 5-1 in Serie A.
This reportedly did not go down well with the boss who ordered a double training session today in order to compensate for the poor performance.
This did not go down well with Eto'o, who reportedly refused.
Sky Sports are now reporting that Eto'o could cancel his contract at the Genoa club after just one week in Italy. If that was the case Eto'o would not be able to play for another team this season, as he would have already featured for two teams in the season - unless he returned to Everton, an unlikely scenario.
However, Sampdoria's president Massimo Ferrero told the press, as reported by Football Italia, that the row was small and Eto'o would be going nowhere:
“There was just a small row between Eto’o and Mihajlovic, a small exchange of opinions.”
Eto'o played 20 games for The Toffees, scoring four goals in that time.
