That came just 12 months after the defender signed a two-year scholarship for the club from non-league.

A whirlwind year began when Mitchell-Nelson impressed during a successful trial period with Blues U18s, featuring in two matches at the end of the 2016/17 campaign.

In the following season he took time to adapt to the rigours of full-time football, but he learnt his lessons quickly after being dismissed against Luton Town to become one of the youth team’s stand-out performers.

Mitchell-Nelson became a regular for the U23 side and having been handed a development contract in the summer of 2019, he linked up with Isthmian League South Central club Harlow Town on a work experience loan.

In February 2020 he made his debut as a sub in the 2-1 win over Lincoln City and featured six times in total at the end of 19/20 season.
