The Blues watched as Arsenal unveiled Noni Madueke, but the event was marred by unexpected blunders fans quickly noticed.
Arsenal officially unveiled Noni Madueke on Friday, July 18, as their latest summer signing completing a blockbuster KSh 9.5 billion move from Chelsea.
The 22-year-old winger was handed the number 20 shirt and is expected to bring flair, speed, and directness to Mikel Arteta’s attack.
The former PSV man, who joined Chelsea in 2023, expressed his excitement about starting a new chapter in North London.
"It's already a great team with a clear identity, and I can't wait to bring my style to the team and try and help the boys as much as possible to take that next step… and grow as a player, but also as a person," Madueke said in his first interview with Arsenal.

However, what should have been a flawless unveiling was overshadowed by a series of avoidable errors.
Arsenal’s media team made several missteps during the launch — and fans spotted every single one. Here are the three biggest mistakes that turned a routine player reveal into an unexpected transfer leak.
3. Revealed Cristhian Mosquera Too Early
While fans admired Madueke’s photos in the new Arsenal kit, one image on Getty sparked confusion and excitement — it featured Cristhian Mosquera, a player Arsenal had not officially confirmed.
The young Spanish defender was seen wearing Arsenal training gear, mid-interview with club staff.

3 Transfers That Could Change Everything for Manchester United
The Red Devils are set for a major summer shake-up with key signings incoming and multiple high-profile exits on the cards.
The image appeared to be from a media day shoot and was clearly not meant for public release. But once it was uploaded as part of Madueke’s unveiling batch, the news was out: Arsenal had quietly completed or were very close to signing Mosquera from Valencia.
This unintentional reveal turned social media upside down. For Arsenal, it meant their secret fifth signing was no longer under wraps — and it shifted attention away from Madueke’s moment in the spotlight.
2. Uploaded Internal Media Files Publicly
The appearance of Mosquera in the images was not just a background fluke — it resulted from Arsenal’s media team accidentally uploading internal files to Getty.
Instead of filtering content specific to Madueke, multiple batches were released, including assets for other signings.
In a world of tightly managed transfer announcements, even a single file mix-up can undo weeks of planning. The premature upload bypassed the usual embargoes and digital control Arsenal is known for.
Though the image was quickly pulled down, it had already been screenshotted, shared widely, and circulated across platforms. Fans now not only knew about Madueke — they had proof that another signing was effectively confirmed.
1. Overshadowed Noni Madueke’s Big Moment
Perhaps the biggest blunder was that Madueke’s unveiling was overshadowed. What should have been a focused, celebratory moment for Arsenal’s newest attacker became a split headline involving a different player altogether.
Madueke’s KSh 9.5 billion move, his new role under Arteta, and his ambitions for the season were all drowned out by the buzz surrounding Mosquera’s unintentional debut.
