The 18-year-old has signed a six-year contract with the Blues, which includes the option of a further year, and will join his new team-mates for pre-season next month.

Kellyman said: ‘It is fantastic to be standing here as a Chelsea player. It’s a massive club with an amazing history, so it is great to join. It is a dream come true for sure. I’m buzzing to have put on the shirt and can’t wait to get started.’

An attacking midfielder, Kellyman started his career at Derby County and spent ten years with the club before signing with Aston Villa in 2022.

The England youth international featured for Villa’s Under-18s and Under-21s during his first season with the club - and earned a nomination for the Premier League 2 Player of the Month award.

Kellyman was part of Villa’s pre-season tour of the United States last summer and made his first-team debut in August 2023 during a 3–0 Europa Conference League victory over Hibernian.

He went on to make five further senior appearances last season, which included Premier League appearances against Manchester City and Crystal Palace.

Welcome to Chelsea, Omari!
