The 32-year-old's trio took his tally for the season to eight goals, a figure bettered for the team lead only by attacking midfielder Eden Hazard, who has 11.
However, despite his impressive performances at Stamford Bridge, Eto'o hopes to finish his career in Palma, where he enjoyed a four-year spell between 2000 and 2004 before moving to Barcelona.
"I'll always like Barca, but I personally prefer Mallorca," the Cameroonian told Cadena Cope. "My son has pressured me to finish my career there, as he is from there.
"I have signed on at Chelsea for the entire season and will try to enjoy it. [But] later on, I will go to Mallorca."
The Balearic Islands outfit, which sits eighth in the Segunda Division after 22 games, was relegated from La Liga last season.
