Leandro Trossard equalized for Arsenal shortly after the break, capitalizing on a cross from Bukayo Saka that missed several Villa defenders and Viktor Gyokeres.

As the game entered added time, it seemed like both teams would settle for a draw, but Emi Buendia scored a dramatic winner in the 95th minute, securing the win for Aston Villa.

The match highlighted the impact of Arsenal's injury problems, particularly in their defense. With multiple center-backs sidelined, including William Saliba and Gabriel, the team's game plan was affected.

Arsenal have used six different center-back partnerships in 22 games this season, and their current back line, consisting of Riccardo Calariori, Piero Hincapie, Jurrien Timber, and Ben White, struggled to gel.

Saliba is expected to return sooner than Gabriel, who is out until the end of December, and Cristhian Mosquera is sidelined until mid-January, which may cause difficulties for Arsenal during the festive period.

The result has implications for the Premier League title race, which was previously seen as a one-horse contest with Arsenal leading. However, with two draws, two wins, and one defeat from their last five games, other teams are closing the gap.

Aston Villa, with five wins from their previous five games, and Manchester City, with their Norwegian goal-scorer, are now strong contenders.

Aston Villa's manager, Unai Emery, has turned the team's fortunes around after a disappointing start to the season, and his impressive coaching skills have sparked a conversation about him being the best coach in the Premier League.

Emery's success has earned him a priority status at Aston Villa, and if the club matches his ambition off the pitch, they may experience significant growth and success.
