The 32-year-old striker, who joined the Blues from Anzhi Makhachkala over the summer, is yet to find the net for his new club despite making five appearances.
And the Cameroon international has vowed to continue working hard to adapt his game at Stamford Bridge.
“Already I have noticed that English football is very physical – more physical than other types of football,” Eto’o told Chelsea’s official magazine.
“It hasn’t been too much time yet, so I need to continue working to make sure I keep improving my level. Every game here is important and I realise that.
“I have come here to enjoy playing for Chelsea and to enjoy the football. I go into every game with the same approach.
“It doesn’t matter where you put me, I will play football. My team-mates are helping me a lot and also the coaches, so I feel that I am settling into the team.”
