Chelsea are in a very strong position to join Manchester United and Tottenham Hotspur in the quarter-finals of the Champions League as they take a 2-0 lead into the second leg of their last-16 tie with FC Copenhagen.
Here, skysports.com looks at the key battles which may prove crucial in ensuring Chelsea do not slip up in front of their own fans.
JOHN TERRY v DAME N'DOYE
Chelsea captain Terry will be looking to cap a great week by keeping out powerful Senegal international N'Doye at the Bridge. Terry looks set to regain the England armband, having been stripped of the honour a year ago following well-publicised off-field issues. The centre-back will undoubtedly be buoyed but will need to maintain his focus to keep out 25-year-old N'Doye, who has so often proven lethal for the Danish side.
JOSE BOSINGWA v JESPER GRONKJAER
While Gronkjaer's career may be coming to a close, Portugal international Bosingwa will need to keep a close eye on the veteran winger. The 33-year-old enjoyed four seasons with the Blues, with whom he established himself as a key player and a fans' favourite. Gronkjaer also had a superb scoring record at Stamford Bridge, meaning Bosingwa will need to put in a strong performance to keep him at bay.
NICOLAS ANELKA v MIKAEL ANTONSSON
Frenchman Anelka may have been a bit-part player over the course of the season, but he certainly made his case for a starting berth after his performance in the first leg. Anelka ensured the Blues stayed in the hunt for silverware with two goals at Parken, extending his remarkable scoring record in the competition to seven goals in six games. The man charged with halting him could be 29-year-old defender Antonsson, who is facing a race against time to feature. With key defender Zdenek Pospech already missing through suspension, boss Stale Solbakken will hope the Swedish defender recovers from a strained buttock muscle in time to feature.
