What will Manchester United fans be looking to see from van Gaal's Holland?

All eyes will be on Holland at the World Cup, as manager Louis van Gaal will complete his final duties as boss before moving to Manchester United.

The Netherlands are in a tough Group B which features Spain and Chile, as well as Australia - who are expected to finish bottom with a very young squad at Ange Postecoglou's disposal. This is widely considered to be one of the more disappointing Dutch sides in recent times, with many of the players coming from the Eredivisie - which many believe to be a weak league.

However, most of the attention will be on manager van Gaal, who is not only one of the most experienced managers in the tournament, but is set to leave his post in the summer ahead of taking the Manchester United job. Red Devils fans are mostly excited over the prospect of the former Barcelona and Bayern Munich manager replacing David Moyes in the Old Trafford hot seat, but many will wait to see how his Holland side fare in Brazil this summer before making an initial judgement.

Van Gaal is a known preacher of free-flowing, attacking football, and it seems the fluidity that comes from pushing such a philosophy has rubbed off on the system Holland play - as just days before Holland face Spain, we still don't know what formation they will use.

It's most likely going to be a 3-4-1-2 system, and United fans will begin to wonder whether that's what beckons for them next season. 

There is unsurprisingly great onus placed on a No. 10 in this system, as Wesley Sneijder will be relied upon to create chances behind United's Robin van Persie and Bayern Munich's Arjen Robben. Fortunately for United, they already have an abundance of those players, with Wayne Rooney, Juan Mata, Shinji Kagawa and Adnan Januzaj all considering it their best position.

United don't have someone with the sheer pace and direct running of Robben though, and whilst Michael Carrick and Marouane Fellaini could play in the centre of midfield, United fans will be looking to see how the Dutch back three - or five, depending on your tactical outlook - will perform.

Left back Daley Blind enables flexibility given that he can play in the centre of midfield too, and United don't have anyone that can do that. The system could be flipped in that Phil Jones can play at right back and in midfield, but with Rio Ferdinand and Nemanja Vidic no longer at the club, van Gaal has to rebuild a defense - which may lend itself to a full-scale overhaul.

Given van Gaal's reputation for playing attacking football, that's exactly what United fans will want to see. After the turgid displays under Moyes, they will want to be given encouragement that flair and expression will be used in the final third, and whilst maybe don't possess that devastating outlet of Robben's pace, it will show the fans the kind of ideas van Gaal has.

Most of all, United fans want to see wins. Holland have a modest squad this time around so expectations need to be realistic, but if they can put on a decent display against Spain, it will give United fans confidence that van Gaal is the man to lead United back to the summit of not only the Premier League, but also the Champions League too - in time.
