Frank Lampard says Chelsea players were delighted with the manner of their Capital One Cup win at Leeds United.
Chelsea flew back into London from the Club World Cup on Monday, but the journey from Japan did not appear to take any toll in the second half, especially once Mata equalised just a minute after the restart.
Lampard said: "We didn't make the greatest preparation but there's no excuse, we had to up it.
"The early goal gave us the impetus, we believed from then on and we didn't think we could lose the game.
"Some of the football we played, we opened them up and showed what we could do."
