Conte's future at Stamford Bridge appears to be in serious doubt following a poor run of form that has seen the Blues win just three out of 10 games in 2018.
Barca travel to Chelsea on February 20 for the first leg of their last-16 Champions League tie, and Valverde believes that critics have been too quick to write off Conte's achievements in England.
"Chelsea's head coach is the one who led them to win the Premier League title last year, he's won many titles, and he's had a great career," the Spaniard is quoted by the Daily Mail as saying.
"Do you want me to tell you what's going to happen in the future? Or about your prediction? At the moment there are no changes so far."
Conte, who has also managed Juventus and the Italy national team, signed a new contract at Chelsea last summer.
