Goals: Lampard 28' (pen), 57', 66', 72', Kalou 42', Joe Cole 64'

England midfielder Frank Lampard struck four goals on Wednesday as Chelsea rebounded from their FA Cup reverse at Barnsley at the weekend to defeat Derby 6-1 in the Premier League.

Lampard, who was left out of Saturday’s match, scored from the penalty spot in the 28th minute after he was fouled by Dean Leacock.

He added three more in the second half to record his fourth career hat-trick and his first for Chelsea.

Lampard’s fellow England international Joe Cole and Ivory Coast’s Salomon Kalou scored the other goals while David Jones notched a late consolation for struggling Derby.

Chelsea moved to within five points of Arsenal, who top the standings with 66 points from 29 games and are two ahead of champions Manchester United, who have a game in hand.

Chelsea: Cudicini, Ferreira, Carvalho, Terry, Ashley Cole, Ballack (Drogba 67'), Makelele (Essien 73'), Lampard, Joe Cole (Shevchenko 74'), Anelka, Kalou.

Derby: Carroll, Edworthy, Stubbs (Leacock 16'), Moore, McEveley, Sterjovski, Ghaly (Earnshaw 52'), Savage, Pearson, Lewis (Jones 58'), Miller.
