Kobbie Mainoo’s name not appearing among Manchester United’s 25-man Champions League squad has understandably raised eyebrows, but there is no reason to assume the academy graduate has been left out of Europe. 👀🔴
The important detail many fans are missing is UEFA’s List A and List B registration system.
📋 LIST A: THE 25-MAN SQUAD
List A is the senior Champions League squad and is subject to strict UEFA registration rules. Clubs have a maximum of 25 players on this list, meaning every available space has to be carefully managed. 📝🏆
United’s submitted List A includes the likes of Bruno Fernandes, Mason Mount, Andrey Santos, Youri Tielemans, Manuel Ugarte, Matheus Cunha, Bryan Mbeumo and Benjamin Šeško.
But that is not the end of the story…
🚨 ENTER LIST B!
UEFA also allows eligible young players to be registered on List B.
And this is where Mainoo comes in. 👀🔥
The Manchester United midfielder was born on 19 April 2005, and United have registered him on the B-list alongside other academy players including Shea Lacey, Harry Amass, Jack Fletcher and Tyler Fletcher.
That means his absence from the 25-man List A should not be interpreted as a Champions League exclusion.
In fact, United’s Champions League squad information confirms that Mainoo is registered on the UEFA B-list and remains available for selection.
😮💨 SO, CAN MAINOO ACTUALLY PLAY?
YES. 🔴✅
A player on List B can still feature in Champions League matches, provided he meets UEFA’s eligibility requirements and is properly registered before the relevant match.
The B-list also gives clubs flexibility because they can register eligible young players without consuming one of the limited List A places.
That is exactly why fans should not look at the 25-man squad and immediately conclude that Mainoo has been frozen out. 🚫
🔥 UNITED ARE BACK IN THE CHAMPIONS LEAGUE!
Manchester United are returning to the Champions League for the 2026/27 campaign, with their league-phase fixtures including meetings with Sabah, Atlético Madrid, Como, Roma, Sporting, RB Leipzig, Bayern Munich and Villarreal.
And Mainoo has already written his name into United’s recent European history, having previously featured in the Champions League during the 2023/24 season.
So when the Champions League music starts ringing around Old Trafford again… don’t be surprised to see Kobbie Mainoo involved. 🎶🏟️🔥
🔴 THE BOTTOM LINE
Mainoo has not been abandoned by Manchester United.
He has not been banned from Champions League football.
He has not been forgotten.
His registration on List B simply means United can keep him eligible for European competition without using one of their precious List A places. 💪🔴
So, Red Devils, put the panic button away! 😂🚨
KOBBIE MAINOO IS STILL IN THE CHAMPIONS LEAGUE PLANS. 🏆🔴✨
