Having progressed through the ranks at Cobham since joining the Academy as an Under-16, Harrison has continued to impress with his development.

Last season, the midfielder played a key role for Harry Hudson's Under-21s as the side won the Premier League 2 league title. He also featured regularly in our Under-19s' UEFA Youth League campaign, helping the young Blues top the league-stage with an unbeaten record.

After recently signing a new contract with Chelsea through to at least 2029, Harrisonwill now gain his first experience of senior football during a season-long spell with Wimbledon, where he will work under manager Johnnie Jackson.

Everyone at Chelsea wishes Ollie the very best of luck during his time at Wimbledon and we look forward to following his progress at the Cherry Red Records Stadium.
