Who says? Who else but Chelsea boss Jose Mourinho, who watched his side overcome a 2-1 first leg deficit to romp to a 5-4 aggregate win over mighty Barcelona.
Chelsea blazed to an amazing 3-0 lead before being pegged back to 3-2 - all before half-time. But then captain marvel John Terry powered the Premiership leaders back to a two-goal advantage on the night.
The glory night for the Londoners started in the eighth minute when a quick break following a Xavi slip, allowed Frank Lampard to slot a right-wing ball to Mateja Kezman, who arrowed the perfect ball into the path of Eidur Gudjohnsen who powered home a right-footer past goalkeeper Victor Valdes.
Then came two goals in quick succession.
The first on 17 minutes saw Lampard pounce on a Valdes spill after a deflected Joe Cole left-footer could not be held by the Barca stopper.
Chelsea moved into dreamland two minutes later when another counter-attack saw them take advantage of an exquisite Cole through ball and Irishman Damien Duff raced into the penalty area, before coolly slotting home under the body of Valdes.
But Barcelona did not panic.
They got back into the game after Paulo Ferreira handled the ball in the penalty area and Ronaldinho slotted home the spot-kick on 27 minutes.
It was the Brazilian who then put the Catalan side ahead on the away goals rule 11 minutes later when he produced an improvised piece of skill on the edge of the Chelsea penalty area.
With the outside of his right foot, he curled the ball past the Chelsea defence and into the net beyond a bewildered Petr Cech.
Chelsea however regrouped and up popped Terry with 14 minutes remaining to power home a free header from a Duff corner to put the Blues into the last eight of the competition.
