Inter are currently 13 points behind league leaders AC Milan.
"I hope that after a bad start to the campaign that we can win the Scudetto again," said Eto'o.
"It's a personal challenge which I think is possible because Inter have the best squad in the Italian championship.
"We've had our problems and although we are 13 points behind with two games in hand, we can do it.
"I want to enjoy the rest of the season and would love to take the title away from Milan."
