Didier Drogba insists he wasn't undermining Chelsea boss Andre Villas-Boas with his halftime talk for their 1-1 draw at FA Cup opponents Birmingham City.

Drogba sought to clarify the matter ahead of Tuesday night's Champions League game at Napoli, explaining he was merely delivering a pep talk in the tunnel on top of Villas-Boas' usual half-time duties.

The 33-year-old, who is set for a recall in Italy, said: "I want to make things clear - the manager made a speech at half-time, and after that, I think he's got some leaders in the team, in the squad. We're here to help him.

"We were just trying to bring the team up. We did what the manager wanted us to do and tried to apply what he was saying. Nothing more.

"People are making a big thing out of nothing."
