Louis van Gaal arrives at Manchester United with an outstanding record of success first in his native Netherlands and subsequently at some of the biggest clubs in the world.
As a manager he has won league titles in three different countries, guided a youthful Ajax side to UEFA Champions League glory, as well as lifting the UEFA Cup. His second stint in charge of the Dutch national team ended with the Netherlands making the semi-finals of the 2014 World Cup, a run which included a magnificent 5-1 win over holders Spain.
Born Aloysius Paulus Maria van Gaal in Amsterdam on 8 August 1951, he joined Ajax aged 20 and while he never played for the great Dutch club's first team, the influence of the time he spent immersed in its culture of Total Football has never left him.
He cut his teeth at professional level after moving over the border to Royal Antwerp in Belgium, but following four years there he returned to Holland to complete his playing career, briefly at Telstar, then for eight years at Sparta Rotterdam before retiring after a short stint at AZ.
