Eto'o won the Champions League in 2010 while playing under Mourinho at Inter Milan.
And earlier this week the Cameroon legend admitted his admiration for the Chelsea boss.
He said: "There is only one Jose Mourinho. I have played under a lot of great coaches - but there is no other character in the game like Jose.
"He is one of the best coaches in the world - and we had a lot of success together at Inter Milan. I would like to have the chance to play under him again - because it is never boring when Jose is around.
"Of course Chelsea are a great team - and when we have all the offers on the table then I will discuss with my agent and see what my next step is."
