Nesta Guinness-Walker, born 30 November 1999 (age 26), is an English left-back whose senior career is still most clearly associated with Reading. That spell gave him his main run of first-team football, with 28 league appearances in the 2022–23 season.
Reading remains the reference point rather than a footnote. For a player still working his way through the professional game, that was the season in which he became a regular rather than just another name moving around the edges of squads.
He is now at Aberdeen, wearing squad number 24. In 2026–27 he has made seven league appearances and six in the League Cup, taking him to 13 appearances in all competitions for the club.
Guinness-Walker’s career to date is a straightforward one: an English left-back best known for his year at Reading, now trying to build another proper run of games at Aberdeen.
