Chelsea head coach Thomas Tuchel is certain his players need to put in "another top performance" if they are to knock Atletico Madrid out of the Champions League on Wednesday. The 'Blues' will take a 1-0 lead to Stamford Bridge after Olivier Giroud scored with a brilliant bicycle kick in the first leg, which was played in Bucharest, Romania. Mason Mount and Jorginho will miss the second leg through suspension, while Thiago Silva and Tammy Abraham are both out injured. Chelsea have yet to taste defeat under head coach Thomas Tuchel - who replaced Frank Lampard in January - and are unbeaten in their last 13 matches in all competitions.
