Riccardo Calafiori is back in Italy this week, this time wearing the Arsenal badge, and the player who returns is a far cry from the one who left for England two seasons ago. When the Gunners secured his services, Calafiori was primarily featuring as a centre‑back for Bologna, and many of the coaches who had overseen his development questioned whether he could ever make the step up to a world‑class left‑back. The doubts have now been erased. Not only is he holding his own on the left flank of a dominant Arsenal side, but, according to former Liverpool and England defender Jamie Carragher, he is "by far the best left‑back in the league." Calafiori's impact is evident on both ends of the pitch.
Defensively, he contributes to an Arsenal back line that has looked almost impenetrable this season, while offensively he has already added goals and assists to his résumé. He opened his Arsenal account by finding the net in the Community Shield triumph over Manchester City, and he has since supplied decisive passes in league victories against Coventry City and Aston Villa. One of his most telling performances came against Chelsea, where a contentious VAR decision ruled out an off‑side goal by Ezri Konsa that would have given Calafiori a second score sheet entry. Nevertheless, his influence on Arsenal's winning goal was unmistakable.
In the build‑up, Calafiori made a diagonal run that forced Chelsea midfielder Christos Tzolis to drift deeper, pulling Pedro Neto into a five‑man defensive line and creating space for Arsenal to dominate possession. As Carragher observed on Sky Sports, "Wherever Calafiori was, Neto was.
When Calafiori drops forward, Neto drops back to make a back five." This positional discipline forced Chelsea to vacillate between a back four and a back five, a tactical uncertainty that Arsenal exploited repeatedly. The Italian's contribution did not stop there. His forward surge into the penalty area dragged centre‑back Maxence Lacroix out of position, opening a 14.4‑metre gap between Lacroix and his partner Wesley Fofana. That corridor of space was exactly what Kai Havertz needed to dummy the ball to Martin Ødegaard, who finished calmly.
The pattern was familiar: a similar sequence unfolded earlier in the Community Shield match against City, where a run from Tzolis, a dummy from Havertz and Ødegaard's finish produced the third goal. In both instances, Calafiori's under‑lapping run created a sizeable opening between the opposition centre‑backs – first between Ruben Dias and Joško Gvardiol, then between Lacroix and Fofana. Carragher summed it up succinctly: "You see the space between the centre‑backs, that comes from Calafiori.
This is the impact he's having on games at left‑back." Yet labeling him merely as a left‑back would be an oversimplification. Calafiori frequently abandons the traditional defensive duties of his position to become an auxiliary attacker.
During the Chelsea encounter, he switched flanks in a matter of seconds, moving from the left side to the right and inserting himself into a completely different phase of play. Former Arsenal winger Leandro Trossard praised this unpredictability, saying, "He pops up everywhere – in the pockets, as a striker – that unpredictability can hurt teams. I know what he can do and where he can pop up in what position.
Sometimes I can play a blind pass to him and I know he'll be there." His chemistry with new winger Christos Tzolis appears to be developing quickly, echoing the rapport Ødegaard displayed with Tzolis in the earlier matches. Calafiori himself acknowledged the importance of these movements, stating ahead of the Napoli clash, "Every season I'm trying to improve these moments on the pitch – where to go and the timing to go in those positions.
I think it's a process that involves the whole team. Otherwise, I wouldn't be able to find myself in those positions." Calafiori is not alone in offering this tactical fluidity. Ben White, Arsenal's other full‑back, also drifts into unconventional zones, at times operating as a hybrid centre‑forward during the Chelsea game. While White tends to retain a more traditional full‑back profile compared with Calafiori's adventurous excursions, his statistical output underscores his versatility: he leads the Premier League in overlapping runs and ranks fourth for under‑lapping runs this season.
White explained his role to Sky Sports, noting that under manager Mikel Arteta, a full‑back must be capable of playing as a central midfielder, a centre‑back, a winger and even a number‑10. When at full strength, Arsenal function like a well‑oiled machine that is a nightmare for opponents to prepare for.
Xabi Alonso, after his Chelsea side suffered a 2‑1 defeat at the Emirates, admitted, "They push you to the limits." Every Arsenal player is required to contribute defensively; no one can be left unmarked for long. Calafiori epitomises why the Gunners are so difficult to contain – his relentless movement, intelligent positioning and willingness to attack from unexpected angles force opponents into a perpetual state of reaction.
This complexity explains why many teams choose to sit deep, adopting a low block to limit the number of Arsenal attackers they must face. When a side decides to press high and engage Arsenal on the front foot, they often open themselves up defensively, as Chelsea discovered. In summary, Riccardo Calafiori has not only adapted to the Premier League but has redefined the left‑back role at Arsenal, combining defensive solidity with a creative, forward‑driving instinct that makes him arguably the best in his position across the league.
