The two sides meet at the Liberty Stadium on Saturday with Swansea knowing that a win will all but secure their top-flight status for another season.
The Swans are currently 16th in the table, eight points clear of 17th-placed Sunderland with just eight matches left to play (although the Black Cats have a game in hand), while Villa are rooted to the bottom of the table after collecting just 16 points all season.
Despite Villa’s struggles that will still be a challenge for Saturday’s hosts and Britton for one knows how important the game is.
“The Aston Villa game is massive,” Britton told the BBC. “It is the biggest game of the season for us, because it is the next one.”
He also had a warning for fans expecting an easy ride considering Villa’s ongoing problems, adding, “In our position we cannot afford to be underestimating anyone.”
They certainly can’t, but Swansea manager Francesco Guidolin will know the importance of putting more space between his side and Sunderland, especially with the Black Cats facing a relegation six-pointer against Newcastle United the following day.
