Brazil legend Kaka has said he doesn't know if Lionel Messi will depart Barcelona, but he can imagine the Argentinian icon playing at another club.
Messi recently voiced his discontent after comments from Barca sporting director Eric Abidal about the Camp Nou squad, forcing club president Josep Maria Bartomeu to reportedly step in between the pair.
Speaking to Sky Sports, Kaka said Messi's motives for his response to Abidal are unclear.
"From outside it's really hard to say something you don't know. I don't know if Messi wants to leave or if he just wants to protect the players as a captain," Kaka said.
