Why Ethan Nwaneri's Arsenal career has stalled: The reason record-breaking wonderkid is being sent to Marseille, how his chances have dried up since he was persuaded to sign new contract and why club insiders aren't worried about his progress

This time last year, Ethan Nwaneri was preparing for a Premier League start against Wolves .

Twelve months on, Arsenal ’s Hale End crown jewel has been deemed surplus to requirements by manager Mikel Arteta - and has now agreed a surprise loan move to Marseille for the rest of the season - a campaign in which Arsenal are chasing trophies on four fronts.

There is no buy option included in a deal which will see him play under former Brighton boss Roberto De Zerbi , so it's not as if Arsenal are cutting ties with a player who also interested Bournemouth and West Ham .

But it is still a sharp contrast for one of the hottest teenage prospects in world football, who had burst on to the scene in September 2022 when he became the youngest player ever to appear in the league, aged 15 years and 181 days, against Brentford .

Fast forward and the 18-year-old has made zero league starts this season, playing for just 166 minutes and failing to make the squad for Arsenal’s last four matches.

That is a far cry from his 26 league appearances last season, including 11 starts. He scored goals in the Champions League, Carabao Cup and Premier League - including a worldie in February to cap off Arsenal's 5-1 home win over Manchester City .

As Arsenal prepare to face Inter in the Champions League , it's worth remembering another high point of Nwaneri's career came as recently as January 2025, when he was man of the match against Girona, capping his first European start with an impressive finish from outside the area.

The sky seemed to be the limit, with the teenager going on to sign a five-year contract in August after months of negotiations. So, what has happened to a player once tipped for a starring role in Arsenal’s immediate future?

The north London club had been desperate for him to commit his long-term future to them from early last year but Nwaneri wanted reassurances on game time. In the end, an agreement was reached and Nwaneri signed a long-term deal. There was relief within the club because there was a real possibility he would have been sold had he not signed up.

Daily Mail Sport understands the club were conscious of interest from rivals including Manchester City and Chelsea.

To ward off suitors and convince Nwaneri and his representatives of a clear pathway, Arteta and the Gunners accelerated his integration into the first-team setup - a plan that included breaking that league debut record. However, sources say that once the five-year deal was signed, Arsenal have adopted a more relaxed approach, comfortable in the knowledge that Nwaneri was now tied down.

Without the immediate pressure of a potential exit, there has been less urgency to play him, particularly with a £67.5million signing like Eberechi Eze, who occupies a similar position, also finding himself on the fringes.

It’s understood the Gunners were keen not to let Nwaneri leave this month having been severely impacted by injuries across their squad. But the youngster’s desire to get minutes for his development, as well as the return of key players from the treatment room, has changed the situation.

Arteta’s comments last month offered a glimpse into the club’s intial thinking. When asked about a potential loan move, he said: ‘Every player is very important, every player has a role, that role can change throughout the season for different reasons, and everybody has to be ready to play.’

And earlier this month, when questioned on how Nwaneri has handled being on the bench, he replied: ‘In the manner that other players have to cope with these kinds of situations, so preparing in the best possible way, I think he's doing it.

‘His attitude has been excellent, and when he's got the chance to play, he proves that I'm wrong, and he needs to play more minutes and help the team as much as possible. Ethan's attitude on that is exceptional. Every time we have a rest day, he wants to train and he wants to be outside and he wants to be in touch with that ball. In that sense, he's top.’

Those close to Arsenal point to the trajectory of William Saliba and argue that a potential loan move does not signal a loss of faith, but rather a familiar development pathway.

Signed in 2019, Saliba was sent out on multiple loans to France, enduring long spells away from north London amid doubts over his long-term role. Yet those experiences proved invaluable. On his return, Saliba established himself as a cornerstone of Arteta’s defence and one of the league’s standout centre backs.

A temporary spell away for Nwaneri in a demanding environment such as Ligue 1 could similarly accelerate his development, providing regular senior football and responsibility that the Gunners cannot guarantee at present. Arsenal will hope that, like Saliba before him, the time away will speed up rather than stall his progress.

But for a teenager once viewed as untouchable, the coming months represent a defining period in Nwaneri's blossoming career.
