Frank Lampard has claimed that Roberto Di Matteo has given Chelsea fresh confidence since taking over as caretaker manager.
Di Matteo filled the void left by Andre Villas-Boas's sacking and Lampard admits that the Italian's simple approach is benefiting the team.
The England midfielder told BBC Radio Five Live: "The number one makes the decisions and he is revelling in making those decisions. He has kept it very simple. It's a case of getting a confidence and passion through the team and, in the results we've had, you'd say he has done that."
Despite not starting Chelsea's Champions League quarter-final win over Benfica last week, Lampard admits that Di Matteo's handling of the situation was far more preferable than how similar decisions were made by Villas-Boas.
"I spoke with Robbie and certainly had no issue with it. I was delighted to get the result we got. I came on in the last 20 minutes, anyway," added Lampard.
The Blues welcome Benfica to Stamford Bridge on Wednesday evening for the second leg of their tie.
