The Spanish champions are in talks with Italian side Inter Milan about a swap deal involving Eto'o, 28 and Swedish striker Zlatan Ibrahimovic, 27.

"I am convinced that the best thing for Barca is for Eto'o to leave," said Guardiola.

"Could I be mistaken? Maybe so. But I am here to make these decisions."

Guardiola added Eto'o's departure would be good for the team.

"I feel that it is best for the club and the team. It's a question of feelings," he stated.

"I am not here to change anyone's character, but I can decide on which players I want to count on for the season.

"After what we won, we had to change the dressing room. I took this decision from my experience as a footballer."

Eto'o had been on the verge of a deal with Manchester City but Mark Hughes's side withdrew their interest last week.

The forward signed for Barcelona from Mallorca for £16m in 2004.
