London - Eleven months on, but with the same coach and broadly the same team, Paris Saint-Germain return to Chelsea on Wednesday seeking to prove their worth as a Champions League force.
In last season's quarter-finals, PSG came to Stamford Bridge leading 3-1 from the first leg and with a huge 13-point advantage in Ligue 1, only to crash out after Demba Ba's 87th-minute strike took Chelsea through on away goals.
This season, a round earlier, the tie is more delicately balanced at 1-1, and it is Chelsea who are dominating domestically, five points clear in the Premier League with a game in hand, while in France, PSG trail Lyon by a point.
