Ivory Coast striker Didier Drogba will make an emotional return to the Stade Velodrome determined to fire Chelsea out of their current mid-season slump.
Chelsea face Marseille in their final Group F game knowing they have already finished top. Marseille have also secured second place and although there is little to play for, Drogba maintains it is important that he and the team begin to improve.
Drogba, now 32, spent just a year at Marseille, scoring 18 Ligue One goals plus another 11 in Europe in 2003-04 after arriving from EA Guingamp.
His goal record made him a cult hero among the Marseille fans and the Chelsea ace has often spoken of finishing his career back at Stade Velodrome.
"I think it is important for me and the team to play better than what we are doing now," said Drogba. "I have been sick for a few weeks. It is difficult to come back to full fitness very quickly.
"But I am really happy with the way I have recovered. I am trying to help the team. I know that I can do better and I have to do better. It is not really about the goals, it is the way I am playing."
