Mexico coach Tata Martino admits his time with Barcelona still burns.
Martino spent just one year in charge at the Camp Nou, during Atletico Madrid's title winning season in 2013/14, before stepping down from his role.
"Big clubs always go through stages of conflict," Martino told MARCA Claro, referring to the tough time the Catalans have endured off the pitch this season, before talking about coming in for criticism.
"It [being criticised] happened to me at Barcelona. In 15 days I went from being good to being extremely bad.
"I don't know if it's something that has to be accepted, but it happens."
