Aston Villa boss Paul Lambert says he's "really disappointed" with their Capital One Cup exit.
Romain Vincelot's header saw Orient join Bradford in humiliating Villa in this competition, with the Bantams famously defeating the Premier League team over a two-legged semi-final in 2013.
And earlier this year at Villa Park, Sheffield United knocked Lambert's men out of the FA Cup.
Asked if the disappointment resembled those defeats, the Villa boss replied: ''You don't want to lose any football game.
''When you lose any football game, it's not a great feeling.
''I'm really disappointed because I though the team I picked was enough to win the game.
''I knew this would be a hard game and I picked a team I thought could win it, and we should have done as we had enough chances.''
