Oscar returns for Blues

Barclays Premier League leaders Chelsea made one change for the St Stephen's Day visit of fourth-placed West Ham, with Oscar included from the start.
The Brazilian playmaker replaced John Obi Mikel following Monday’s 2-0 win at Stoke, giving the Blues more guile against a Hammers side criticised for playing “football from the 19th century” by Jose Mourinho last season on their visit to Stamford Bridge.
