He turned professional in November 1990 and made his league debut in the old Division One against Everton on 2 March 1991 as a substitute for Denis Irwin. His first league start in 1990/91 also proved a memorable occasion, scoring his first ever goal (albeit via a huge deflection off Colin Hendry) in a 1-0 win over City.
Giggs' first senior trophy arrived in November 1991 as United beat Red Star Belgrade in the European Super Cup final. He picked up his second winners' medal five months later as the Reds beat Nottingham Forest in the League Cup final. The following season, 1992/93, saw Giggs and United win the inaugural Premier League title.
Ryan was an integral part of two Double-winning sides, in 1993/94 and 1995/96, before going one better in 1998/99 by adding the European Cup to the FA Cup and Premier League trophy. His contributions to the Treble-winning campaign included a superb solo goal to win the FA Cup semi-final replay against Arsenal at Villa Park, commonly regarded as one of United's greatest ever goals. Ryan celebrated 10 years at Old Trafford with a testimonial match against Celtic in 2001/02.
