Bottom club Aston Villa and relegation strugglers Newcastle United have conceded more second-half injury-time goals over the past four seasons than any other Premier League clubs, according to statistics reported by the Mirror.
Villa looked doomed for relegation to the Championship as they sit eight points adrift of safety, whilst the Magpies are in the bottom three on goal difference.
It has been a season of woe for Remi Garde's side, with the claret and blue club losing 16 of their 26 league matches this season, whilst Newcastle have suffered defeat in 14 of their domestic fixtures.
It appears that a fundamental problem for both sides is an inability to perform until the final whistle, with the Mirror reporting that no other clubs have conceded more goals in added time than the two strugglers.
According to statistics published by the paper, Villa have conceded 15 goals beyond the 90 minute mark across the last four seasons, while Steve McClaren's side are not far behind, having shipped 12 last-gasp strikes.
Villa's total means that they have the second-worst average in that department of any top-flight team since 1992, with only Cardiff City having conceded more goals per season after letting in an injury-time goal at an astonishing rate of once every 3.8 matches in their solitary season in the Premier League.
Late defensive lapses have also been a problem for the Birmingham club's local rivals West Bromwich Albion, who have conceded a total of 11 in the extra minutes.
Meanwhile, Arsenal have scored more injury-time goals than any other side during the Premier League era, with Danny Welbeck's last-gasp winner over Leicester City last weekend taking their total to 18.
