Benitez enjoyed first day with Chelsea players
Benitez is convinced he can bring out the best in the Blues squad.
"I spoke with John Terry today and it was quite positive. He's a winner, I'm a winner. It's simple.
"I met Frank Lampard briefly yesterday, I spoke with Ivanovic, Cech, Luiz. Some of them I speak to in Spanish because they can understand me better.
"The team is scoring goals and they have some very good players in attack. But they have made some mistakes at the back so we have to find the right balance.
"It's not easy to get the correct balance between scoring goals and not conceding. We need to find the defence but not lose our creativity.
"I am not going to make huge changes. I have a lot of respect for the decisions of Roberto Di Matteo. He had many good ideas.
"Every manager picks a team which he thinks is going to win the game. Roberto had seen them train every day and wanted to pick a strong team.
"Afterwards it can look wrong but he knew his mind and I can't criticise any manager who was doing things the right way."
