The Manager: Louis van Gaal
One of the most successful managers of the modern era, van Gaal moved from Ajax to Barcelona in 1997 where he reunited with many of his former charges from the Champions League winning side.
He won two La Liga titles with Barca in his initial three seasons in charge, before returning for a less successful time there following a brief period as manager of the Netherlands national side – during which they missed qualification for the 2002 World Cup.
Van Gaal then won the Eredivisie with AZ Alkmaar in 2008/09, the Bundesliga with Bayern Munich in 2009/10 and then led the Netherlands to the World Cup semi-finals in 2014. Most recently, he was fired by Manchester United after an unsuccessful run there and has since spoken openly about retirement.
