Villa into semis with win vs. Norwich
Arsenal required a late equalizer by Thomas Vermaelen to take fourth-tier Bradford to extra time in the other quarterfinal, which finished 1-1 after 90 minutes.
Austrian striker Andreas Weimann scored in the 79th and 85th minutes for Villa, before Christian Benteke completed the win in second-half stoppage time.
Norwich, on a nine-match unbeaten run in the league, went in front through Steve Morison in the 19th only for Brett Holman to equalize two minutes later.
It sealed a successful return to Carrow Road for Villa manager Paul Lambert, who left Norwich in the summer and is still in a legal wrangle with his former club.
