Career
Magherafelt–born McFadden played in Ireland for Moyola Park and Ballymena United Allstars. Following graduation McFadden headed to the Icelandic Úrvalsdeild, where she played for Fylkir, then Grindavík. At the end of the 2010 Icelandic season, McFadden and international team mate Rachel Furness left Grindavík for Sunderland.
In June 2012 The Belfast Telegraph newspaper reported that three Northern Ireland players including McFadden had been selected in the 18–player Great Britain squad for the 2012 London Olympics.
But McFadden quickly denied the report: "I haven"t received anything about being in final squad. Wish it was true but unfortunately not." When the final squad was named, no Northern Irish or Welsh players were included.
On 13 January 2016, it was announced she was leaving Sunderland after five years serving the club and signing with Durham.
