The 28-year-old has been criticised by Blues fans for his lack of consistency during the course of the season but McEachran is adamant that the Spaniard still has what it takes to make a difference.
"I think Rafa Benitez can definitely win round the fans and do well at Chelsea," he told The Guardian.
"If anyone can get Fernando Torres, who is still a great player, back to his very best it's him.

"The Spain players all tend to be like that. It's one of the reasons why Andres Iniesta is my role model."
McEachran, who is currently on a season-long loan at Middlesbrough, says he is relishing playing regular football under Tony Mowbray and is optimistic he can help his side win promotion.
"This loan has definitely been the biggest step forward in my career. I've been involved in almost every league game and, hopefully, we'll win promotion," he added.
"I love playing for Tony [Mowbray], I like his whole philosophy, the way he just wants to get the ball down and play. I've fitted in very easily.
"Everything's top-class here, it's so enjoyable. Middlesbrough is really a Premier League club just waiting to get back up there and although Tony didn't have much money to spend last summer what he's done with the bit he had has been unbelievable."
