Ramires returns to Chelsea

Chelsea make four changes from the side that went down 2-0 to Everton at Goodison Park last weekend. Bosingwa, Essien and Lampard all drop to the bench as Andre Villas-Boas chooses to give Gary Cahill only his second start for the club, whilst Ramires and Jon Obi Mikel are restored to the starting line-up.Ashley Cole picked up a calf injury during the defeat and is expected to be out for a prolonged period. It offers a chance to Ryan Bertrand, who starts today. The visitors, Birmingham, make changes of their own, with five new faces from the side that drew blanks last week against Hull City as manager Chris Hughton looks to shake things up. Colin Doyle, Pablo Ibanez, Nathan Redmond, Morgaro Gomis, and Adam Rooney are all drafted in for Boaz Myhill, Steven Caldwell, Jonathan Spector, Chris Burke and Marlon King respectively
