The defining moment of his playing career came in the 1988 FA Cup final, when he scored the winning goal for Wimbledon against Liverpool, producing one of the biggest upsets in the competition's long history.
Career highlights as a manager include taking Wycombe Wanderers on a memorable FA Cup run that climaxed in a semi-final against Liverpool and driving Northern Ireland from a FIFA ranking of 124th to 27th; a period during which he notched up notable results against England, Spain, Denmark, Sweden and Portugal.
Liverpool came close to jeopardising Wimbledon's dream again in the second half when they were awarded a penalty, only for John Aldridge's shot to be saved by Dons goalkeeper Dave Beasant.
He is believed to be the first player to be sent off for a professional foul, after committing a deliberate handball in a Football League Trophy match against Oxford United in 1982.
Roy's famous winner for Wycombe Wanderers against Leicester City at Filbert Street has since become a goal of FA Cup folklore.
By the time he left, Northern Ireland were top of their Euro 2008 qualification group and reached an all-time high position of 27th in the world.
[12] Notable results during his tenure included a 1–0 victory against England in a World Cup qualifying match,[13] a 1–1 draw against Portugal,[14] who went on to reach the 2006 World Cup semi-finals,[15] a 2–1 win over Sweden,[16] and a 3–2 win against eventual Euro 2008 winners Spain in a Euro 2008 qualifying match, with striker David Healy scoring a hat-trick.
[20] Sanchez signed four Northern Ireland players, David Healy from Leeds United,[21] Steven Davis and Aaron Hughes, both from Aston Villa,[22][23] and Chris Baird from Southampton.
Many of the players who were signed by Sanchez, such as Baird and Hughes, started for Fulham in a Europa League final against Atletico Madrid a couple of years later.
[29] In the 2011–12 season, the club struggled to stay in the League despite reaching the Area Final of the Johnstone Paint Trophy before losing to Swindon Town.
[33] He met the players for the first time on 18 November 2013 whilst also giving the club's official website his first interview as Apollon Smyrni head coach.
