FAC: Chelsea 3-1 Ipswich Town
A brace from Michael Ballack and a Frank Lampard free-kick put Chelsea into the fifth round of the FA Cup after a 3-1 victory over Ipswich.
But the Premier League side again made hard work of overcoming lower-league opposition in a domestic cup competition.
Chelsea had already been bundled out of the Carling Cup on penalties by Burnley and were taken to a replay in this competition by League One side Southend.
