**AFC Wimbledon have signed Chelsea's promising teenage midfielder Ollie Harrison on a season-long loan.**
Harrison, 18, who is an England age-group international, was included on the Chelsea bench for the Carabao Cup tie against Lincoln City last season.
It was his fourth first-team matchday involvement having also been an unused substitute for the Premier League game at Manchester City in 2024-25 and against Leeds United and Leicester City in the FA Cup the same season.
"I'm really excited to play here for Wimbledon. It's a massive club with massive hopes," [he told the club website, external](https://www.afcwimbledon.co.uk/news/2026/july/31/afc-wimbledon-sign-chelsea-s-ollie-harrison-/).
"I want to demonstrate my top qualities which are my range of passing and leadership qualities."
He added: "I had a good season last season at Chelsea so this season I was desperate to get out into the men's game and when a top club like Wimbledon comes along it's hard to say no."
After leaving Newcastle United three years ago, he excelled in the Chelsea youth system and was a regular for the under-21s.
"Ollie is a young, exciting player with huge potential," said Wimbledon manager Johnnie Jackson.
"He's a technical, ball-playing midfielder with a good range of passing and gives us another great option in the middle of the park. He had a lot of interest from other clubs so we are delighted that he chose to come to Wimbledon."
