Steve Bruce spoke to club TV following the FA Cup defeat to Peterborough.
His views are in full below.
On a disappointing result having gone 1-0 up...
Going 1-0 up was probably our downfall. We thought it was going to be easy.
We haven't done enough with or without the ball, and consequently we've lost a Cup tie to a team in a division below.
And rightly so, too. We have to be honest.
The better team won and that's the disappointing thing for me.
There's no excuses. No disrespect to Peterborough but I've picked a team I thought could win the game.
We haven't been able to do it.
On the issues we faced in the second half...
We were lacklustre, people were struggling with their fitness levels and it all caught up with the young ones a bit.
I could have made six or seven substitutions, which is disappointing. Peterborough have had 20 shots on our goal.
That means we haven't done enough without the ball, which is usually what we pride ourselves on. At least we have in my time here.
From the moment we scored to the last minute, we looked open and there was no sense of urgency to do the basics well.
On a big lesson for the youngsters...
Hopefully they'll learn from it and realise how hard it is to make a living in this game.
In that respect, it's a good learning curve for them.
They've learnt the hard way.
On John Terry and Andre Green's return...
I left John on the pitch when I was planning to only use him for 60-70 minutes.
But it was good to see him back after 10 weeks.
It was always the plan to get Andre and Henri Lansbury half a game each. In that respect, it was difficult to manage.
But at least we've seen them on the pitch, which is good going forward.
On the afternoon as a whole...
It was a horrible afternoon. It's not nice to be the manager of Aston Villa on days like today.
I thought we'd left these days behind us.
We haven't done enough to win a Cup tie and it's disappointing.
