After making 55 appearances for Newcastle United in all competitions, Anderson debuted in a January 2021 FA Cup loss to Arsenal before heading to Bristol Rovers on loan a year later.
That spell proved a pivotal stage in his development—and included what may still be the most memorable match of his career.
Glenn Whelan, the former Republic of Ireland international who served as a player-coach at Rovers, recalls how Anderson’s assured but humble demeanor made an immediate impression. He says Anderson arrived and instantly looked different: calm under pressure, eager to be tested, and never one to shrink from a challenge.
Whelan highlights 5 February 2022 as a key moment. Rovers were away at Sutton United, a rugged, in-form side. Trailing at half-time, Whelan pushed to bring Anderson on, convinced he could change the game. Anderson came off the bench, won a penalty, and Rovers earned a draw. From then on, he was virtually ever-present.
Anderson’s mindset and work ethic stood out throughout his time at Rovers. He played primarily off the left, constantly demanded the ball, handled tight marking, and created chances. He loved training, stayed late for extra work, and showed the hunger of a future top player.
He signed off in style on one of the greatest days in the club’s history. On the final day, Rovers needed to better Northampton’s result or win by five more goals—and they did, triumphing 7-0. Anderson scored the seventh with five minutes left, lifting Rovers into the top three for the first time all season. He left the pitch carried aloft by jubilant supporters.
