* He will start the game, says Ancelotti
* Chelsea rest Anelka and Cole (Adds Ancelotti quotes, byline, changes dateline)
MARSEILLE, France, Dec 7 (Reuters) - Chelsea striker Didier Drogba will try not to let his heart rule his head when he makes his eagerly awaited return to the Stade Velodrome for Wednesday's Champions League clash against Olympique Marseille.
"I am a bit overwhelmed by all this but it's okay," Drogba told Marseille's website (www.om.net) on Tuesday. "I try not to mix everything but I am so overwhelmed by so many emotions I don't really know how to deal with this situation.
"It feels funny. It is the first time I have been in this kind of situation."
Chelsea coach Carlo Ancelotti, however, said Drogba would be in the team for Wednesday's game.
"He will start, I'm not crazy," the Italian said. Drogba, who has not been at his best recently, scoring only two goals for his club from open play since August, ruled out a return to OM.
"I have been with Chelsea for more than six years and it looks like I'll end my career here, even if Marseille is tempting," he told a news conference on Tuesday.
