Chelsea cruised through to the 4th round of the FA Cup, with Ramires recognised as one of the standout performers.
The Italian spoke of how he enjoyed the way the Brazilian midfielder took his second of the game.
"He helps things," said Di Matteo of the 24-year-old.
"I don't think he is the only one as we have a few goalscoring midfield players.
"I very much enjoyed the second goal he scored today. We are very pleased with it and we deserve a few goals as well."
Ramires signed for Chelsea from Benfica in 2010.
