Jose Mourinho gambled on the fitness of striker Samuel Eto'o as Chelsea looked to overcome a two-goal deficit to advance to the Champions League semi-finals ahead of Paris St Germain.
Eto'o, who has scored all 11 of his Chelsea goals at Stamford Bridge, missed the past three games with a hamstring injury, including the 3-1 quarter-final first-leg loss at Parc des Princes last Wednesday.
Four changes were made from the side which beat Stoke 3-0 on Saturday, with David Luiz, Eden Hazard and Oscar included alongside Eto'o.
PSG replaced injured talisman Zlatan Ibrahimovic with Lucas Moura in their solitary change from the first leg.
Chelsea: Cech, Ivanovic, Cahill, Terry, Azpilicueta, Luiz, Lampard, Willian, Oscar, Hazard, Eto'o. Subs: Schwarzer, Cole, Torres, Mikel, Schurrle, Ba, Kalas.
PSG: Sirigu, Jallet, Alex, Thiago Silva, Maxwell, Verratti, Thiago Motta, Matuidi, Lucas Moura, Cavani, Lavezzi. Subs: Douchez, Cabaye, Marquinhos, Menez, Digne, Van Der Wiel, Pastore.
