Alex compares Ramires to Essien
The 23-year-old, who finalised his £18.2m move from Benfica last week, has been described by manager Carlo Ancelotti as "the future for Brazil and Chelsea".
Alex believes Ramires has a similar style to midfield powerhouse Essien, who recently returned from a serious knee injury.
"He's not as strong as Essien, but he has the same style on the pitch. He goes forward very quickly, then he comes back and marks very well. He's a very good player.
"It's very important for me and the team that the midfielders go to shoot and arrive at the goal, but then get back to mark. He's almost the same as Michael Essien like that, so I am expecting a lot of goals, which is important for us.
"He will get to play with Michael Essien, John Obi Mikel and Frank Lampard. We have a very good midfield group and he will do a great job for us."
