In his first month as coach, at the end of the 1993–94 Rugby Football League season West secured the First Division Premiership Trophy against Castleford, and then traveled with the team to Brisbane, guiding them in their 1994 World Club Challenge victory over Australian premiers, the Brisbane Broncos in front of a WCC record attendance of 54,220. At the end of his first full season, he and the team won the League Championship, Challenge Cup, Regal Trophy, and Premiership - the 'Grand Slam' of all 4 trophies. Even though Wigan dominated rugby league from 1985 to 1995, it was the only season the club achieved this feat.
