No less than six Chelsea players have an injury cloud hanging over them ahead of their Champions League clash with Benfica.

Branislav Ivanovic is the biggest doubt for the second leg at Stamford Bridge after he was sent for a scan on his hamstring on Monday.

Daniel Sturridge, Ashley Cole and Didier Drogba all missed training at Cobham with injury concerns. Drogba is believed to have injured his toe.

Goalkeeper Petr Cech skipped some of the session and Frank Lampard was also given treatment at the training ground.
