Noa Lang won’t be anywhere near the pitch when Napoli take on Arsenal in their Champions League group stage opener on September 9. The Dutch winger was dropped from the squad entirely due to disciplinary reasons, adding yet another chapter to what has become one of the more expensive cautionary tales in recent Serie A transfer history.

For a player who arrived at Napoli for a fee exceeding €25 million from PSV Eindhoven just over a year ago, the trajectory has been almost perfectly downward. Being excluded from a marquee European fixture isn’t just a bad look. It’s the kind of moment that tends to define how a player’s tenure at a club is remembered.

A transfer that never found its footing

Lang signed with Napoli on July 17, 2025, with bonuses potentially pushing the fee even higher. The expectation was that the left winger, who had been electric at PSV, would slot into Antonio Conte’s system and add creative firepower to an already dangerous attack.

During the first half of the 2025-26 Serie A season, Lang managed just one goal across 18 appearances. His struggles were widely attributed to difficulty adapting to Conte’s tactical demands, a system that requires full-backs and wingers to operate with defensive discipline that doesn’t exactly play to Lang’s strengths as a flair-first attacker.
