Upon signing his first professional contract, Bolton promptly activated an option clause in his contract to extend for a further year. In 2022, he embarked on a short-term loan agreement with Atherton Collieries, competing in the Northern Premier League Premier Division. On 25 May 2023, he committed to a new one-year contract with Bolton, with an option for an additional year. Expressing his admiration for Finlay, Bolton manager Ian Evatt remarked, “His talent is without question, he is a very talented kid.. He is a talented young man and we’re lucky to have him”.
