Defending champions Manchester City will also fancy their chances of advancing after being handed a home clash against Championship Sheffield Wednesday who beat top-flight Burnley 1-0 on Tuesday.

In Wednesday night's other games, last-year's beaten-finalists Sunderland beat Birmingham 3-0 and will face Stoke, who were also 3-0 victors over Portsmouth.
