A Manchester native, defender Borthwick-Jackson became a Manchester United player at just 6 years old, joining the Red Devils' youth system in 2003 and remaining at Old Trafford ever since.
As he aged, Cameron developed into one of the most promising of England's young players, representing the Three Lions at Under-16 and Under-17 levels between 2012 and 2014.
During the 2015-16 season, Borthwick-Jackson was elevated to the United Under-21 squad, earning a place in the Under-19 and Under-20 England sides too. In addition to these call-ups, he was also promoted to the senior United team, making his first team debut on 7th November 2015 in a 2-0 win over West Bromwich Albion at Old Trafford.
In conjunction with winning the Under-21 Premier League title, the manager Louis van Gaal gave Cameron 10 Premier League appearances before the end of the season. His total of 14 matches impressed the Club enough to be awarded the Denzil Haroun Reserve Team Player of the Year award for 2015-16 — a trophy also won by players such as John O'Shea (2001-02), Darren Fletcher (2002-03), Giuseppe Rossi (2005-06) and Adnan Januzaj (2012-13).
With José Mourinho replacing van Gaal that summer, Borthwick-Jackson found playing time limited and instead would join Championship club Wolverhampton Wanderers for the first half of the 2016-17 season. He made just 7 appearances for the Molineux side and returned to Old Trafford for the remainder of the campaign.
In 2017-18, Cameron joined Championship Leeds United on loan but made just 6 appearances before again reuniting with the Red Devils.
He dropped to League One for the 2018-19 term, making 33 appearances and scoring 2 goals for Scunthorpe United as the Iron were relegated to League Two at the end of the season.
On 2nd September 2019, Tranmere manager Micky Mellon brought Cameron to Prenton Park on a season-long loan deal that will see him remain with the SWA until May 2020.
Interesting Fact: Cameron's first and second senior goals came in the same game, Scunthorpe United's 5-3 victory over Charlton Athletic on 2nd October 2018.
