The Cameroon legend left Anzhi for Chelsea on transfer deadline day.
Roberto Carlos recalled to Globo Esporte: "With the arrival of Eto'o in the locker room, there were a few small problems to solve.
"I had to explain to several players this transfer. Then came a time when Samuel was affecting my work. He wanted to control the club, to take my place and towards Guus Hiddink, the coach, he acted downright cowardly.
"I've known Eto'o since he was 16 and I've always appreciated him. He is a good person, but he still thinks of himself and not of the group.
"When a player, instead of playing, is interested in recruiting and those players are his friends, this is somewhat confusing and strange. He did everything for Anzhi except play football."
