Di Matteo hailed his Chelsea players for once again "blanking out" a scandal engulfing the club after watching them thrash Norwich 4-1.
He said: "I think the results are telling us that we are able to blank things out surrounding us externally and that we could focus on what is our aim and target and job, to win football games.
"It's proven how professional the group is and how well they respond to it."
"No, I don't think so," he said.
"That's not what we feel or what is happening with us.
"We concentrate on our strength and we try to win games with the players that we have and with a football philosophy that we're aiming to play.
"At the moment, the team is a healthy form, we are creating lots of chances, we are scoring lots of goals, and with different goalscorers as well.
"We don't rely on just one player, so it's a team that is in good shape."
