Benjamin Arthur, born 9 October 2005 (age 20), is an English central defender whose early senior path took him from Brentford to Celtic in February 2026.
His Celtic spell was brief but not empty. Arthur made four league appearances in 2025-26 and was part of the squad that won the Premiership that season, giving him a Scottish title before the rest of his career settled elsewhere.
Portsmouth has since become the main thread of his senior football. In 2026-27, he has made six Championship appearances and one in the FA Cup, taking him to seven appearances in all competitions for the club.
Arthur remains a developing defender rather than a finished article. His current market value is around £85,000, according to Transfermarkt, and his career so far is a modest one: a Celtic title on the record, followed by regular first-team exposure at Portsmouth.
