Liverpool’s John Arne Riise scored a spectacular early volley, but Chelsea fought back. A Steven Gerrard own goal (a rare error from the Liverpool captain) levelled the scores. The game went into extra time, and with three minutes remaining, Didier Drogba rose to head home the winner from a corner. The 3-2 victory (after a late Liverpool goal) gave Mourinho his first trophy as Chelsea manager. It was the catalyst for belief.

Chelsea stormed into a 3-0 lead (Gudjohnsen, Lampard, Duff) to lead 4-2 on aggregate. Then, Barcelona roared back to 4-2 on the night (4-5 on aggregate) thanks to Ronaldinho's genius. But in stoppage time, powered home a header from a corner to make it 5-4 on aggregate. The 4-2 victory was a raw, emotional, and ferocious display of Chelsea’s fighting spirit.
