The hosts were ahead in the quarter-final through Frank Lampard´s strike, before Crouch launched a two-footed, knee-high lunge at Mikel John Obi - the type of challenge the Professional Footballers´ Association want to see eradicated.
Crouch has been linked with a move in January, and the three-match ban he faces will take the England striker into the transfer window. His dismissal virtually ended Liverpool´s chance of continuing their fine recent cup results against Chelsea, while Lampard´s strike silenced the travelling fans. Andriy Shevchenko doubled the lead in stoppage time to complete victory.
