The Cameroon striker spent one season working under Guardiola at Barcelona before transferring to Italian giants Inter, where he played for his current Chelsea manager Jose Mourinho.
But in an astonishing verbal attack on Guardiola, Eto’o stated that the current Bayern Munich boss rarely spoke to him at Barca, insisting that he used other players to communicate instead.
“I first of all reminded Guardiola that he'd never been a great player. He was a good player, that's true. I told him,” Eto’o told BeIN Sport.
“As a coach, he had proven nothing. He came in and didn't even know the story of the dressing room.”
During his time at Camp Nou, Eto’o stated that Guardiola stripped him off the number nine shirt – which the Cameroonian considered a “lack of respect” - and advised the striker to move to Uzbekistan.
“Guardiola has never had the courage to say things in front of me. He passed by the players. Xavi told me they wanted me to stay but I had to talk to Pep. I say 'never, if you do not respect me, I do not respect you',” Eto’o continued.
“He shook hands with me when I was at Inter and I played against Barca, but this was just for the cameras and TV. Behind the scenes before the match, he did not greet me."
The 33-year-old, who has netted on eight occasions for the Blues in the Premier League this term, also said Guardiola only spoke to him on three occasions during the 2008/09 season – one of which was to tell Eto’o how to perform as a striker.
“Pep told me how to move like a striker. I told him: 'You're not normal!' The true story is that Pep didn't respect the things in football.”
