Birmingham City 23-24 Training Kit Unveiled - Sponsored by Undefeated?
Birmingham City have given us a first glimpse at their new 2023-24 training collection this week, and possibly have hinted at a sponsorship deal with US-based sneaker store and apparel brand Undefeated.
Birmingham City 23-24 Training Kit
This picture shows the Birmingham City 2023-2024 training jersey being worn by new signing Koji Miyoshi.
Based on Nike teamwear, the Birmingham City 2023-2024 training shirt is royal blue with dark blue accents in the form of the collar and a graphic on the sleeves. The Swoosh is white.
The most unique feature of the jersey is the sponsor, which appears to be the aforementioned Undefeated brand. The text "UNDFTD" - the same writing is often used by Undefeated - is written across the front of the shirt, matching the navy of the collar.
Birmingham City have not released any official statement about the sponsor but it looks like the presence of the logo on the training kit can be seen as a sort of teaser ahead of an official announcement. There remains a chance that this is not about the sneaker store, however.
The logo of previous main sponsor, betting brand BoyleSports, does not feature on the Birmingham City website so it's safe to assume that the deal has ended.

Special Rayados 'Legado 86' Commemorative Kit Released
Mexican side CF Monterrey and Puma have officially unveiled a special commemorative jersey, titled the Jersey Legado 86. Celebrating the 40th anniversary of Monterrey's first-ever Liga MX league championship won in the Mexico 1986 tournament, the commemorative shirt made its on-pitch debut during their 26-27 Liga MX match against Cruz Azul.
The shirt's defining characteristic is the substitution of the modern club crest with the classic 1986 retro emblem, which showcases the historic mountain silhouette, vintage football, and classic club lettering. Puma positioned their red cat logo and the retro crest to replicate the arrangement seen on the original 1986 jersey, while modern club partners such as BBVA and Codere are incorporated across the traditional navy and white stripes.
Several bespoke detailing elements complete the design, including a star graphic with the number 86 printed inside the collar and the current Rayados crest positioned on the nape of the neck. Released in a limited run of 1,986 pieces, the collector's item pays homage to one of the most celebrated moments in the club's history.

Puma Kit Durability Questioned Again as Julian Ryerson Suffers Ripped Shorts
Borussia Dortmund full-back Julian Ryerson suffered an unusual kit malfunction during BVB's 1-0 Bundesliga victory against VfB Stuttgart. Midway through the second half, the Norwegian international engaged in a physical duel with Stuttgart winger Jamie Leweling. As Leweling fell to the turf, he grabbed hold of Ryerson's shorts, completely tearing the outer seam apart and leaving the fabric hanging loose.
Ryerson initially attempted to carry on playing by knotting the shredded material at his hip. After repeatedly signaling toward the bench that the damaged kit could not hold up, he eventually made his way to the sideline. Second-choice goalkeeper Alexander Meyer rushed over to hand him a fresh pair, resulting in a brief moment where Ryerson was left in his base-layer yellow undershorts before donning the replacement gear and re-entering the pitch.
The incident has brought Puma's kit durability back under scrutiny. The German brand constructs its authentic elite kits using lightweight Ultraweave performance fabric, prioritizing minimal weight and high breathability. However, the delicate material has repeatedly faced criticism among supporters after tearing in high-intensity tussles, with Ryerson's mishap marking another visible tear on the Bundesliga stage this 26-27 season.
Monterrey Debuts Special Coca-Cola 100th Anniversary Kit Font
CF Monterrey sported a special commemorative nameset on their 26-27 Puma home kit during their Liga MX match against Cruz Azul at Estadio BBVA. The bespoke squad numbers and lettering were created in collaboration with longtime club partner Coca-Cola to celebrate the company's 100th anniversary in Mexico (1926-2026).
The font features an eye-catching textured look inspired by traditional Mexican artisan beadwork. Rendered in a bold red base adorned with intricate white, green, and red jewel-like accents reflecting the national flag, each number also integrates a subtle Rayados crest at the base. Positioned neatly above the numbers is the official red Coca-Cola 100 México anniversary script and lockup.
Alongside its on-pitch appearance with the first team, the commemorative nameset was released as an exclusive collector's edition. Only 100 supporters were given the opportunity to customize their 26-27 home shirt with the special font directly at the official Estadio BBVA club store.
