Regular left back in the side, Fitzpatrick began his career at Stockport County, eventually moving to Northwich Victoria in 2010 where he stayed for two seasons. Securing a loan move to New Mills AFC, David eventually made the move permanent in 2012.
In 2013, Fitzpatrick moved onto Southport, after passing a trial. Proving a successful move, he earned himself an England C call-up, going on to make three appearances for the national side. As well as this, Fitzpatrick finished the season in the Non-League Paper’s conference Premier Team of the Year.
He joined Macclesfield in 2015 and has since secured his place in the team at left back. Fitzpatrick has been virtually ever present since and signed a new deal in the summer of 2017 after helping the club to the FA Trophy Final in the 2016/17 campaign.
