Former Ajax, Barcelona and Bayern Munich manager van Gaal is currently in charge of the Dutch national team, but has already announced that he will leave his post after the World Cup in Brazil this summer, with former Chelsea boss Guus Hiddink set to replace him.
This means that van Gaal, 62, will return to club management this summer, and is the firm odds-on favourite to replace Moyes at Manchester United, who was sacked by the Red Devils last week. The experienced Dutchman will now be charged with the task of turning United around, with a summer of big spending expected.
United have slipped from Premier League champions to fighting for a Europa League place, leading the club to conduct a full scale squad overhaul this summer - which van Gaal will now be in charge of as United seek to return to the summit of English football next season.
Some have already speculated that van Gaal will seek to bring some of his players from the Holland national team to Old Trafford, and no player will be linked with a move more than Galatasaray star Wesley Sneijder, who has been a reported Manchester United target for around three years.
Dating back to his time at Inter Milan, United have been reportedly keeping a keen eye on the former Ajax star, and as a key part of van Gaal's Holland side, those rumours are no doubt set to resurface as the summer transfer window draws ever closer.
But in van Gaal's 4-3-3 system with features a classic No. 10 playmaker, he already has Wayne Rooney and Juan Mata who perform better there. Adding another one into the mix wouldn't solve any of United's midfield problems, rather making them even more complex.
Additionally, van Gaal has been critical of Sneijder throughout his reign as Holland boss, first suggesting that the ex-Real Madrid star was displaying poor fitness and wouldn't be selected until he got in better shape, and most recently saying that unless he performs better in the run up to the World Cup, then his place in the side is far from guaranteed.
Whilst a fan of the playmaker and the ability he has, it seems van Gaal has reservations about Sneijder's application and with younger, and arguably more impressive players already in that position, it would be a surprise to see Sneijder arrive at Old Trafford this summer - even with van Gaal seemingly on his way.
