Samuel Eto'o has revealed he once vowed he would NEVER play for Jose Mourinho.

The former Barcelona striker said he had a "tense" relationship with the Portuguese boss before they worked together at Inter Milan where they won an unprecedented treble of Serie A title Champions League and the Coppa Italia.

Eto'o was reunited with Mourinho when he joined Chelsea from Russian side Anzhi Makhachkala on a one year deal at the end of August.

It was a move Eto'o himself would once have never have agreed to.
