Arsene Wenger restored his big guns to the Arsenal attack for the Champions League quarter-final, second leg at Highbury.
Thierry Henry and Jose Reyes - who recovered from a swollen ankle - returned in place of Jeremie Aliadiere, while Ashley Cole replaced Gael Clichy as part of three changes to the team which lost to Manchester United in Saturday's FA Cup semi-final.
With the match standing at 1-1 after the first leg, Chelsea coach Claudio Ranieri abandoned his usual policy of tinkering and kept faith with the team which beat Tottenham 1-0 in the Premiership on Saturday.
