Having completed and confirmed Joao Pedro's deal, Chelsea have reportedly signed a new left-back. As per METRO, the Blues have signed Kian Best on a free transfer after he left Preston at the end of last season.
Best began his career at Preston before moving to Bohemians on loan earlier this year. His return from loan marked the expiration of his contract at Preston, and he has now left the club as a free agent.
Having departed Preston, the aforementioned report claims that Best has completed his medical and signed a contract at Chelsea. The English left-back is also expected to join the development squad in a bid to gather experience and gain match fitness.
As a left-back, Best is a versatile defender due to his proficiency to feature at centre-back and the defensive midfield region. At Preston, he registered most of his appearances either as a left-back, left midfielder, or centre-back. Thus, his flexibility to take up different roles on the pitch could benefit Enzo Maresca's side.
Best could also be seen as Ben Chilwell's replacement at left-back. This comes after Chilwell has been linked with a move to Napoli as per Alfredo Pedulla (via Caught Offside).
During his loan move to Bohemians in the 2024-25 term, Best made just one appearance. At Preston, Best made 17 appearances, scoring two goals and delivering one assist.
