LONDON: Carlo Ancelotti believes Didier Drogba and Nicolas Anelka's revitalized partnership will strike fear into the hearts of Chelsea's Premier League title rivals.

The Italian manager saw his new charges extend their perfect start to the season with a 2-0 victory at Fulham on Sunday, sealed by a goal in each half from Drogba and Anelka.

The pair have not always gelled successfully during their time together at Stamford Bridge.
