Peterborough United Wembley winner has quit professional football at the age of 24

Peterborough United Wembley winner Oscar Wallin has confirmed his retirement from professional football at the age of 24.

The PT revealed Wallin was likely to retire when he walked out on Posh early in October to return to his Swedish homeland. Posh and the player eventually agreed to cancel his contract by mutual consent.

Centre-back Wallin moved to Posh from Swedish second tier side Degerfors IF in July 2024. He signed a two-year deal, but lasted just 14 months and 45 appearances with the highlight a starring role in the 2025 Vertu Trophy Final win over Birmingham City at Wembley last April.

Wallin’s last appearance for Posh was the 2-0 League One defeat at Wigan Athletic in August.

Wallin confirmed his retirement in Swedish newspaper Sundsvalls Tidning. Wallin said: “I have no desire any more. Technically, I could take it up again, but I have no desire for it at the moment.

“I have no interest in playing in Sweden either. I feel I want to do things I have sacrificed or neglected over the last 15 years because I have played football, so yes I have now stopped playing.

“‘I've really never planned anything in football. I just took it as it came, but I've known for a long time that I wouldn’t play until I'm 35. Now I’ve stopped at 24, but it could just as well have been 27 or 22.”

Wallin has a degree in economics and it’s understood a career in banking is now a possibility.

Wallin is the second Posh man from that 2-0 Wembley success over Birmingham City to retire. Goalkeeper Jed Steer also quit in the summer to take up a career in media at the age of 32.
