The forward has revealed how Arsenal expressed a keen interest in signing him before Luis Aragones persuaded him to sign for Mallorca.
“I met Luis at a crucial moment in my life where I had to take the right direction – and thanks to him I did,” Eto’o said.
“I was about to sign that very afternoon at Arsenal and maybe I would have never been the player I am today.
“Luis picked me, then I ended up joining Barcelona. That decision changed everything.”
Eto’o went on to sign for Barcelona, and later Inter Milan – where incidentally he played under his current boss Jose Mourinho – having huge success at both clubs.
Eto’o was part of the Barcelona side that claimed two European cups in 2006, and 2009.
He then went on to play a crucial part in Inter Milan’s famous treble campaign under Mourinho in 2010, in which he earned his third Champions League winners medal.
The Cameroon international has spent the last two years plying his trade in Russia for Anzhi Makhachkala, before Mourinho came calling once more this summer.
Now 32, Eto’o made his Chelsea debut during Saturday’s 1-0 defeat to Everton.
