Ramires says the make-up of Chelsea's squad is perfect.
Brazilian midfielder Ramires joined Chelsea over the summer in an £18m deal and has started the club's last two Premier League games.
Ramires said: "The team is playing excellent football and have virtually no faults.
"We destabilise opponents with goals in the opening minutes of every game and it shatters their plans for us.
"It's five wins from five games, but we know the Premier League is long and hard - a lot can happen between now and the end of the season."
