With a host of players, purchased or promoted to first-team action, Chelsea FC can now look at fielding a variety of different midfield formations. Gone are the days when Lampard, Ballack and Essien virtually pencilled their own names into the starting line-up. Now, with a little bit of imagination, common-sense and a dash of adventure thrown in, Chelsea's midfield can morph into a multitude of forms.

Chelsea will travel to Manchester under immense pressure to progress to the semi-finals. United, on the other hand, are favorites to progress now, having won the first leg at Stamford Bridge 0-1. Will this be Carlo Ancelotti's best match as a Chelsea manager in Europe or his last?
