Aston Villa manager Paul Lambert called for an immediate response from his players after they conceded four second-half goals at Southampton.
Lambert's men led 1-0 at half-time though Darren Bent's toe-poked effort but capitulated after the break and
went down to a 4-1 defeat
at St Mary's.
"The chant 'there's only one Nigel Adkins' was echoing around St Mary's after their terrific second-half performance here. What a day for Saints as they get lift-off in the Premier League. Southampton are in business. What on earth did Adkins say to his players at the break? They struggled in the first half."
"If you're not bang at it, that's what can happen," he said.
"We deserved to go one-up at half-time but you have to sustain that. In the second half it wasn't good enough."
Lambert now wants his side to pick themselves up ahead of a trip to the Etihad Stadium on Tuesday night to face Manchester City in the Capital One Cup, before a local derby against West Brom on Saturday.
"Now we pick ourselves up and go again. I never get too high when we win and I never get too despondent when we lose," he said.
"They [the players] gave us the effort and I can't fault that. We will keep cracking on.
"It's important to try and keep a level head. It's a long, long season and I'm sure there will be ups and downs."
