Riccardo Calafiori returns to Italy with Arsenal this week, showcasing a transformation from his initial days at Bologna, where he primarily played as a centre-back. Two years later, he has emerged as a standout left-back, with Jamie Carragher declaring him "the best left-back in the league by far."

Calafiori has not only solidified his defensive role but also made significant contributions in attack. His impressive start to the season includes:

• Scoring in the Community Shield win over Manchester City
• Providing assists in league victories against Coventry and Aston Villa

During a recent match against Chelsea, VAR denied him a goal, but his influence was evident as he played a crucial role in Martin Odegaard's winning goal. Carragher noted how Calafiori's strategic positioning coerced Pedro Neto into a back five, illustrating his impact on the game's dynamics.

Calafiori's versatility extends beyond traditional left-back duties; he often functions as an extra attacker, seamlessly transitioning across the pitch. Former Arsenal winger Leandro Trossard remarked on Calafiori's unpredictable positioning, which poses challenges for opposing defenses.

This tactical flexibility is not unique to Calafiori; Ben White also plays a vital role in Arsenal's attacking structure, contributing to their fluidity on the field. Arsenal's strategy under Mikel Arteta demands that full-backs possess skills across multiple positions, making them a formidable opponent.

As Arsenal continues to dominate, Calafiori exemplifies the tactical evolution that makes them a nightmare for rivals, proving why many teams resort to a low block against the Gunners.
