Paul Lambert has labelled the home clash with Hull next weekend a "cup final" as they strive for the victory that he believes would ensure safety in the Barclays Premier League.
Lambert says the Tigers clash is a "must-win" as Villa lie 16th in the top-flight table on 35 points, two places off the drop zone.
His comments follow the 4-1 defeat to Swansea at the Liberty Stadium, a loss he believes was defined by the second goal scored by Jonjo Shelvey.
He said: "I am really disappointed to lose, really disappointed.
"We started the game really well. We lost a goal but we deservedly got right back into the match with a really good one ourselves. We got ourselves back into it.
"We then lost a poor goal. That second was a major turning point. It was a great finish but it was an error on our part.
"There wasn't much too much in it at that time. The second goal was the major turning point though.
"We weren't too despondent going in at half-time.
The third goal took the wind out of our sails. The fourth goal was disappointing. Gabby had a similar one that wasn't given in the first half.
"We still need one more win.
"It's a must-win match next week. The lads know how big it is. It's a cup final. We have to win it.
"There are three really tough games to finish. It's not a position we want to be in. But we are. Next week's is a must-win."
