After winning the Champions League with Real Madrid and the World Cup with Germany, the next challenge in Sami Khedira's career is to step into the shoes of a veteran and become a Chelsea legend. Frank Lampard has left the Blues this summer following 13 glorious seasons at Stamford Bridge and there is suddenly a vacancy in the Blues's engine room. With David Luiz also departing for Paris Saint-Germain, there is a real opportunity for Khedira to step into the breach and make the defensive midfield role his own at the west London club, and cement himself as a fan favourite much like his predecessors did. Khedira has done it all during his short career - he's won league titles in two different countries and won the World Cup - the most prestigious honour on the international stage. His next mission is to form part of a new-look Chelsea midfield next season as the Londoners enter a new era under these uncertain post-Frank Lampard days.
