Linesman gives Riccardo Calafiori a throw-in lesson during Arsenal’s 3-0 win over Nottingham Forest

Arsenal returned to winning ways with a 3-0 Premier League victory over Nottingham Forest at the Emirates Stadium, and a lighthearted linesman-player exchange drew attention as much as the goals.

Martin Zubimendi scored twice to open his account for the club with a volley and a second strike, and Viktor Gyökeres added a third to seal the win for Mikel Arteta’s side. The match also produced a brief, 25-second interaction in which Arsenal left-back Riccardo Calafiori was shown how to take a throw-in by a match official.

Video captured by a fan circulating on social media showed the linesman offering a step-by-step demonstration of the throw-in technique, with Calafiori mirroring the movements and then returning to play. The exchange was brief and took place during routine stoppages in the match. Observers described the moment as humorous rather than confrontational; there was no visible disciplinary action related to the incident and play continued.

Calafiori, 23, has been a regular presence for Arsenal since his move to North London. He has contributed both offensively and defensively this season, recording one goal and two assists in four Premier League appearances and helping the team secure three clean sheets in those matches. Teammates and club staff have featured him prominently in the left-back role as Arteta’s side balances attacking width with defensive solidity.

The victory marked a response to recent results for Arsenal and extended a positive run at the Emirates. Zubimendi’s opening goal arrived from a well-taken volley that gave the home side an early platform, and his second compounded Forest’s difficulties as Arsenal controlled possession and tempo. Gyökeres’ finish late in the game put the result beyond doubt.

Nottingham Forest, managed by Ange Postecoglou, struggled to carve out clear chances against a compact Arsenal back line. The visitors pressed at times but were unable to convert opportunities into goals, and their defence ultimately yielded to Arsenal’s attacking movement.

The throw-in episode quickly became a talking point among supporters online, adding a light note to the match coverage. Players and officials frequently interact on technical matters during fixtures, and in this instance the demonstration and Calafiori’s receptive response drew attention for its informality and brevity rather than any on-field controversy.

Arsenal will look to build on the win as the Premier League schedule continues, while Nottingham Forest will aim to regroup following the loss. Both clubs face busy fixtures in the coming weeks as the domestic season progresses.
