Didier Drogba, Joe Cole and Ricardo Carvalho will all return to the starting line-up against West Ham on Sunday, says manager Carlo Ancelotti. The Italian is able to welcome his top scorer back after Drogba sat out Wednesday's 2-1 win against Portsmouth, while Cole and Carvalho are back in after being rested in midweek. 'I don't want to change a lot of things about the next game, Carvalho returns to play and I have to take a decision on midfield,' Ancelotti said. 'Mikel or Ballack I want to do recovery and Joe Cole will return to play. 'Drogba is good, he trained yesterday and today is fit and he will be ready for Sunday. Alex didn't train today but will train tomorrow and the other players stay well. For Sunday we also have Sturridge, who is doing a very good job, two fantastic weeks in training, and will be ready to play.' Missing however is Michael Essien, whose hamstring injury looks likely to rule him out of Chelsea action until as late as the end of January, owing to the African Cup of Nations which begins on January 10, with the Ghanaian likely to be called away by his country before the end of the year. In other news, Ancelotti dismissed media speculation linking us with Atletico Madrid's Sergio Aguero. 'It is not true because we don't sign a contract with any players, at this moment we do not think to buy Aguero,' said the 50-year-old.
