Middleton joined Posh from league rivals Loughborough Lightning at the start of the 2023/24 season. The forward also had a previous spell at Nottingham Forest Women and made over 50 appearances. The midfielder is always positive on the ball, keen to bypass defenders and create chances for herself or others. The number 7 is soon to reach 50 appearances for the club; scoring just shy of 15 goals in that time.
