PAUL Lambert insisted Aston Villa's display at The Den on Friday night warranted an FA Cup replay after Millwall snatched a place in the fifth round right at the death.
John Marquis scored a dramatic winner in the 89th minute to settle a full-blooded contest and heap further pressure on Lambert after a nightmare week.
The Midlands club were still reeling from their shock defeat in the Capital One Cup to Bradford City in midweek but the Villa boss thought his players responded well.
They went in front through Darren Bent's fifth goal of the season midway through the first-half, but Danny Shittu equalised with a towering header five minutes later.
"I don't think we deserved to lose the game," Lambert said. "I could not see that late goal coming. But in saying that, when you go 1-0 up you can't lose a goal from a corner again.
"It's individual errors that are hurting us at the minute. We were not prepared to get hurt to defend a bog-standard corner and that's disappointing.
"We had a lot of the ball and I didn't think either team was going to win it. My players weren't hiding so I was quite pleased with that aspect. I thought we were heading for a replay."
