Chelsea manager Avram Grant is under pressure and he needs to win the Champions League to have any hope of retaining his job.

Here, PA Sport looks at some of the confrontations that could decide the outcome.

JAMIE CARRAGHER V DIDIER DROGBA

Carragher is an old hand when it comes to big European nights. He has strength and great organisation and is not daunted by any opponent. The Liverpudlian has blossomed into one of Rafael Benitez's most consistent performers.

Drogba has not had the easiest of seasons, disrupted by injury and the African Nations Cup, and he has been consistently linked with a move away from Stamford Bridge at the end of the season. However, the Ivory Coast striker - although not as prolific during this campaign - is a huge threat because of his power and pace and ability to either thrive alone or bring others into play.

STEVEN GERRARD V MICHAEL ESSIEN

Gerrard is one of the most influential midfielders in England and his contribution to Liverpool is enormous. The Reds skipper is equally adept at defending as attacking and he covers a huge amount of ground in every game. His advanced midfield role can make him very difficult to mark freeing up team-mates and unbalancing the opposition. The England midfielder also has a fierce shot and his scoring contribution is vital to the team.

Essien has proved himself to be flexible after filling both in defence and midfield this season. He would have no problem playing as a defensive midfielder with his tenacious tackling and energy. Essien also has a ferocious shot himself.

FERNANDO TORRES V JOHN TERRY

Torres has made an instant transition to English football after his move from Atletico Madrid. The Spaniard has an all-round game to trouble any defence with his pace, dribbling, ability in the air and clinical finishing.

Terry is pivotal to his side's stability and the team will rely on his customary leadership. Although he has had a mixed season punctuated by injury, off-field criticism and losing the England captaincy, the defender has immense influence and 100% commitment and can knit the side together in the face of pressure.
