Last season, although Arsenal boss Mikel Arteta was heavily criticized for his overall performance in the Premier League, one thing cannot be denied. He was the one who made the team’s defense stronger than ever.

Looking back at Unai Emery’s 2018-2019 season, the big Gun conceded 51 goals. That making it the ninth worst record in the league.

When it came into the hands of Arteta in the first season to make a full team. He conceded just 39 goals, the third best in the Premier League.

Even though it looks successful But the Spanish boss continues to make changes to the defensive line for the better which we will see in the 2021-2022 season.
