The former Barca defender, now with Palmeiras, said: "I am very surprised. He is the best in the world. A goal scorer, fast, with presence in the area. He was an excellent teammate and motivates people.
"If it is because something has happened between him and someone involved with the directors or the coach, I do not know, I am not there, but he is the best striker there.
"I would not change Eto'o for anybody. He is a much better player than (Zlatan) Ibrahimovic."
