Authoritarian manager Louis van Gaal has a global reputation as one of the top managers in world football. He boasts tactical flexibility (4-3-3 at Ajax, 2-3-2-3 at Barcelona and 4-4-2 at AZ), but has retained an attacking philosophy regardless of whether he is competing in Holland, Spain or Germany.
He likes wide players, high-lines and dominating the possession of the ball.
Van Gaal also has won nine major titles from three different countries, with four Eredivisie titles, a brace of La Liga honours, the Bundesliga, a Champions League trophy and UEFA Cup win to his name - yet seven of those all arrived prior to the turn of the millennium. For some, it is very much a case of 'what have you done for me lately?'
At 62-years-old, van Gaal has a detractor in renowned former Liverpool striker Robbie Fowler, now 39, who enjoyed his most prolific years in the 1990s - the same period when van Gaal was at his most successful.
He told talkSPORT: "I think with Holland and the World Cup, everything is spot on, he's nailed on to be next manager [of Manchester United].
"For me, is he the right man at United? I don't know if he is to be honest. He's had his time, it sounds silly but I think he's too old.
"You can't argue with what he's achieved and what he's won but I think they need a young and vibrant manager."
