Chelsea's stunning Champions League semi-final victory over Barcelona on Tuesday night came at a heavy price as four players earned yellow or red cards that will rule them out of next month's final against either Bayern Munich or Real Madrid.
Here, we look at those who will be missing and what impact it might have on Roberto Di Matteo's side.
The captain's needless first-half red card for clashing with Alexis Sanchez will deny him the chance of redemption for his penalty shootout miss in Moscow four years ago, a mis-kick which cost Chelsea their first chance at Champions League glory. But putting his personal disappointment aside, the loss of their defensive leader will surely leave a hole at the back that Chelsea - given their other absentees - will struggle to fill.
Ivanovic, who played most of Tuesday night's match as Chelsea's only regular centre-half, talked himself into a suspension when he was booked for dissent for his reaction to the award of a penalty for Didier Drogba's foul on Cesc Fabregas. Lionel Messi missed the spot-kick, but the punishment will still be felt by Ivanovic, who did not seem to realise the implications of the booking until he was told during a television interview after the match. With Gary Cahill hobbling off on Tuesday night with a muscular injury and Chelsea anxiously awaiting the results of tests, the loss of Ivanovic and Terry means they will need the injured David Luiz to shake off his own hamstring problem, while Jose Bosingwa could yet be press-ganged into centre-half duty once more.
The Brazilian midfielder found himself playing much of Tuesday night's match at right-back in Chelsea's reshuffled backline. However, he still managed to get forward to score the dramatic first-half stoppage-time goal that would have been enough to send Chelsea through before Fernando Torres' late strike made sure. His audacious chip over Victor Valdes came after he was booked for dissent late in the first half, meaning he already knew he would not be part of the final he was helping Chelsea to reach.
The Portuguese midfielder will pay a heavy price for the 90th-minute booking he received for a late sliding tackle on Javier Mascherano. But the price Chelsea might pay remains to be seen as his absence alongside Ramires will rob Di Matteo of two of his more versatile midfield options. Florent Malouda, Michael Essien, Oriol Romeu and Salomon Kalou are the players that might stand to benefit, but all have suffered from either injuries or indifferent form and they are likely to leave Chelsea more vulnerable in the middle of the park.
