Arsenal's ideal backline for the coming season

Wing-backs - Sead Kolasinac and Hector Bellerin

Arsenal FC v Chelsea FC - Premier League

On the left side of the defence is Sead Kolasinac. Two years ago, Arsenal signed the Bosnian on a free transfer when he left Schalke 04.

The 26-year old has been one of the better performers for Arsenal last season as he made 36 appearances for the Gunners. Averaging just over a tackle per game and one key pass per game, he finished the season with seven assists in all competitions.

While he is capable of making strong contributions in the defence, Kolasinac would need to work on his concentration and his attacking prowess. While he is capable of marauding down the left flank, he needs to cause more havoc in the opposition defence by making better passes and increasing his accuracy.

Notably, he took an average of one shot every two games, but none of it yielded any goal throughout the season.

His counterpart, Hector Bellerin, is well-known for his unbelievable pace. 24-year-old Bellerin has been one of Arsenal's most consistent defenders, especially throughout last season.

Making more defensive contributions than Kolasinac, he averaged more than one interception per game, nearly two clearances per game, and over one aerial duel won per game.

Alongside his defensive capabilities, the Spaniard contributed to eight goals for the Gunners. He has a keen sense of giving the final pass, and also averaged a good 84% pass accuracy in the Premier League.

While his capabilities are unquestionable, Hector Bellerin will need to build on his tackling and heading. However, he is still young and he has a lot of time to work on his abilities. This season, Emery will certainly keep him at right-back for every important game.
