London - Chelsea were drawn to face Leeds United in the League Cup quarter-finals on Wednesday, shortly after beating Manchester United 5-4 at Stamford Bridge to reach the last eight.
Leeds, English football's fallen giants, have beaten Premier League opposition in the two previous rounds, sinking Everton in round three before Tuesday's 3-0 win at home to Southampton.
"Leeds and Chelsea have a bit of history, so it should be an interesting game," said Chelsea coach Roberto Di Matteo.
Bradford City, of third-tier League Two, were rewarded for beating top-flight Wigan Athletic on penalties with a home tie against Premier League powerhouses Arsenal.
After winning 3-1 at Liverpool, Swansea City will face second-tier Middlesbrough, while the only all-Premier League tie of the round sees Norwich City host Aston Villa.
The matches are due to take place in the week beginning December 10, although Chelsea's trip to Leeds will take place on December 19 due to the European champions' involvement in the FIFA Club World Cup.
Quarter-final draw for the English League Cup:
Leeds United v Chelsea
Swansea City v Middlesbrough
Norwich City v Aston Villa
Bradford City v Arsenal
