Frank Lampard revealed a dressing-room discussion at half-time sparked Chelsea’s revival as they came from behind to beat Leeds 5-1 in the Capital One Cup quarter-finals. Chelsea had trailed to a Luciano Becchio strike but turned the match at Elland Road around with goals from Juan Mata, Branislav Ivanovic, Victor Moses, Eden Hazard and Fernando Torres. “We upped it,” said Lampard on Sky Sports News. “In the first half we weren’t at our best, a bit slow with the tempo of the game and we gave a away silly goal that allowed them to score. “Once we upped it with a bit of pace in our game you could see a big difference. “We had a word with ourselves at half-time.” 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.
