One of Europe's most decorated managers, Louis van Gaal has managed some of the biggest clubs in the world across a distinguished 31-year managerial career.
Van Gaal returned Ajax to the European summit as he led the Amsterdam club to UEFA Champions League glory in 1995, and they came agonisingly close to defending their continental crown as they were beaten by Juventus on penalties in the 1996 final.
The Dutchman subsequently moved to Barcelona, where he won La Liga twice before taking charge of the Netherlands national team and then returning to the Catalan giants.
After two years away from the dugout, he enjoyed a hugely successful four-year spell with AZ Alkmaar before taking over at Bayern Munich. Van Gaal had a second and third stint in charge of the Netherlands, which sandwiched a two-year spell as Manchester United manager.
The six most expensive signings Van Gaal made during his managerial career were at Manchester United.
Angel Di Maria's then-British record deal worth £59.7 million (€75.6 million) is the most expensive as the Argentine joined from Real Madrid.
Anthony Martial's purchase from AS Monaco ranks second, ahead of Luke Shaw and Ander Herrera. Morgan Schneiderlin's arrival from Southampton ranked fifth, ahead of the arrival of Van Gaal's compatriot Memphis Depay.
Ranking seventh is Mario Gomez, who Van Gaal signed for Bayern Munich from VfB Stuttgart in 2009.
Brazilian Sonny Anderson comes in eighth after he joined Van Gaal's Barcelona from AS Monaco in 1997, and he is one of two Barcelona signings to make the list alongside Rivaldo.
Arjen Robben's €25 million (around £22 million) move from Real Madrid to Bayern Munich in 2009 was Van Gaal's ninth most expensive signing.
