William Irwin (born 23 July 1951) is a Northern Irish former professional footballer, currently working as director of soccer at the University of Portland and head coach of the United States women's under-23 side.
Prior to his death Tully had recommended Irwin to his former club Celtic but the move never materialised and he eventually joined Welsh side Cardiff City in 1971.
Irwin held the position of first choice goalkeeper for four seasons, beating off competition from Parsons and Jim Eadie, until the arrival of Ron Healey in 1974 saw him lose his place.
[4] After his retirement Irwin took up an assistant manager role at the University of Portland alongside former Cardiff teammate Clive Charles.
The five starting goalkeepers who have trained under Irwin, Greg Maas, Kasey Keller, Stuart Dobson, Scott Hileman, Curtis Spiteri and most recently Luis Robles, have all gone on to play professional football.
