Maill joined Shelbourne in December 2025 from Swedish top-flight side Degerfors IF.
The 24-year-old arrived at Tolka Park having experienced football across the Swedish pyramid and at Real Murcia in Spain.
An extremely tricky ball-carrier, Maill loves to create opportunities and to take defenders on one-on-one. Speaking after completing his move to Tolka Park, Lundgren said he was excited by the opportunity to join Shelbourne and test himself in a new league: “I’m very excited to sign for Shelbourne. It’s a club with a strong identity, big ambitions and passionate fans. I’m ready to contribute and make an impact. Let’s go Reds!”
