From Sedgehill School in Catford, who Fulham have a partnership with, Jaydn Mundle-Smith can play left-back or centre-half. He made his debut for the Under-18s in 2015/16.
In the 16/17 season he nailed down a spot in the starting lineup on the left hand side, and was on target for Mark Pembridge's side.
In the 17/18 season he made 20 appearances for the Under-18s. He made an astonishing 116 recoveries, won 91% of his tackles and made 17 interceptions.
Mundle-Smith made his Under-23 debut against Norwich City in March 2018, coming on at Carrow Road for Marlon Fossey. He made his first start for the Under-23s side in the last match of the season away at Newcastle.
In January 2020, the defender joined Maidenhead United on an initial one-month loan which was extended by a further three months after impressing with the captain's armband at PL2 level.
