Di Matteo signed a two-year contract with the Blues on wednesday.
“Chelsea’s board made the right decision, it would have been a risk to do anything different,” Ramires told Globo Esporte.
“A different manager would need time to know the players and might not adapt.
“Di Matteo managed to make Chelsea play the way he planned and won the world’s most important club competition.
“Thus, he deserves to be regarded as one of the most important managers nowadays.”
