Chelsea keeping close check on Drogba

Chelsea forward Didier Drogba will be closely monitored by the club's medical staff this week, after injuring his right knee over the weekend.
The Ivory Coast international, who was due to link up with his national team this week, has instead remained in London for treatment after picking up the injury in Chelsea's 3-0 win over Bolton on Saturday, the club confirmed on Monday.
Drogba was replaced by Fernando Torres towards the end of the encounter at Stamford Bridge, having scored the Blues' second goal.
The 33-year-old's fitness will be of great concern to manager Andre Villas-Boas whose side travel to West Bromwich Albion in the Premier League this weekend, before facing Birmingham in the FA Cup, Stoke in the league and a return Champions League last 16 tie against Napoli in a busy two-week spell.
