As the group action enters the second half, AS Roma will be looking to gain supremacy over group C by defeating Chelsea at home after their emphatic performance at the Stamford Bridge on Matchday 5 when the two sides face each other. To do so they'll need to transfer some of their domestic defensive solidity to the European stage.

The German is confident of taking three points from the Olimpico.
Atletico's surprise 1-1 draw at home to Qarabag means Chelsea's qualification hopes are not too badly compromised but, given Conte's recent agitation regarding questions over his future in west London, this was an ill-timed and punishing reverse.

An ill-judged backpass across goal by Kolarov presented Alvaro Morata with a chance to level - the Spain striker blazing over - before Roma sprung forward to double their advantage nine minutes before the break. He won the Coppa delle Fiere [Fairs Cup] [the goalkeeper actually played against Chelsea in this tournament on another occasion], which at that time was the name of the UEFA Cup, and also the Coppa Italia. The Frenchman's presence would make it a lot less easy for Roma to dominate the centre of the park as they did last time out.
