Lambert was keen to emphasise that the entire Villa team, rather than just the defence, had to take responsibility for the last two results and expressed his confidence that they will be able to bounce back.
He said: "I believe they will do it. There is no pressure on these lads at all.
"They will go again and give us everything - they will.
"Even though people got carried away before about us beating Norwich and Liverpool, I never did and neither did the team.
"We never let them get too high or too low, because the nature of football is that you can get hurt at any moment.
"We had a good chat the other day with them. For a lot of them, this is their first crack at Premier League football.
"It is not just the defence - it is everywhere. It is unfair to criticise the defence.
"We are in this together, and collectively we have to stop this - not just the defenders."
