Chelsea defender David Luiz has hailed the effect interim manager Rafa Benitez has had on his game since arriving at the club.
Prior to this season, Luiz had often come under criticism for the inconsistency in his performances since joining the Blues from Benfica in 2011.
However, this term the Brazil international has grown in stature and cemented himself as a mainstay in Chelsea's first team, often featuring in midfield for the club.
And Luiz believes all the praise for his transformation should be reserved for Benitez, who took over from Roberto Di Matteo in November.
"I try my best all the time. Rafa Benitez has helped me a lot. I love the philosophy he puts to the Chelsea players," Luiz told Chelsea TV.
"He changed my game and helped a lot. He loves football and he sees football like me. He wants to play with the ball, he wants to press high and wants to try things.
"He gives me confidence to try some things, like shots and passes to help the team. He knows my football, so I like that."
