Dubbed the new Xavi, Clasie has enjoyed a recent rise to stardom with both club and country.
The 22-year-old played a pivotal role in a Feyenoord side which qualified for the Champions League having made 32 appearances in the league.
His form did not go unnoticed with Louis Van Gaal selecting the youngster as part of his squad for the World Cup and with Kevin Strootman out injured, Clasie’s role will be of a greater importance.
It has been a quick rise for the midfielder who, in 2010, spent a season on loan at relegation threatened Excelsior where he helped them survive the drop.
His performances at Excelsior helped him secure a first team place upon his return to Feyenoord and he made 36 appearances, scoring 2 goals, in the 2011/12 season.
That season also saw him get his first Netherlands cap in a World Cup qualifier against Turkey and he was also named on the stand by list for the Euro Championships.
Dogged in the tackle and an excellent passer of the ball, Clasie’s skills will come in handy in Brazil where Van Gaal will hope to implement his brand of total football.
Van Gaal obviously rates Clasie highly having given him his Netherlands debut and making him a crucial part of the squad.
With Clasie needing a bigger stage to develop his talents further, Van Gaal may opt to bring him to Old Trafford to help improve United’s midfield.

The winger turned midfielder has grown from utility player to one of the first names on the team sheet for both Germany and Bayern Munich.
Schweinsteiger received his first cap for Germay in 2004 when he was called up to play against Hungary in a friendly and was later picked to play in the Euro Championships in the same year, where he impressed enough to become a regular member of the squad in future tournaments.
The midfielder was a key part of a Germany side which thrilled many in the 2006 World Cup. He played a crucial role in helping his side to a third place finish.
By the end of this World Cup, he had 41 caps to his name and at the age of 22, this was a record number for any German player at this time until Lukas Podolski broke the record.
As time went on, Schweinsteiger was used more sporadically by manager Joachim Low, who preferred Podolski on the left of midfield instead, but found himself back in the starting line up by the quarter finals of Euro 2008, where he scored one and set up two in a 3-2 victory over Turkey.
He became undroppable and went on to start in the final against Spain which Germany lost 1-0 but it took until the World Cup in South Africa for Schweinsteiger to become the heart of Germany’s midfield.
Thanks in part to then club manager Van Gaal who moulded Schweinsteiger into a central midfielder, he was in sensational form going into the tournament having helped Bayern Munich to a domestic double.
His form gave Low reason to believe that Schweinsteiger could replace the injured Michael Ballack in the centre of midfield, which he did to perfection.
He helped to inspire Germany to yet another third place finish in the tournament and was named on the shortlist for the Golden Ball award, thanks to his three assists he provided during the World Cup.
Since then, he has been the first name on the team sheet for Germany but at club level, he is facing something of a crossroads.
With Guardiola not favouring the experienced midfielder due to his inability to relay the ball fast enough, Van Gaal could yet nip in and sign a player who he helped to redefine his career.

The Portuguese midfielder has shot to fame this season in Portugal helping his club side Sporting Lisbon secure Champions League qualification.
The defensive midfielder, who spent last season on loan at Cercle Brugge, made the central midfield position his own and was named player of the month four times this season, cementing his place as one of the best players in Portugal.
A player in the mould of Yaya Toure, Carvalho is equally capable of using his physique to drive the play forward and is equally adept at putting the ball in the back of the net, highlighted by his four goals this season
His form earned him a call up to the Portugal squad for the World Cup play off qualifiers and he managed to make his debut in the second leg against Sweden. What he has done at club level has not gone unnoticed as he has been named in the World Cup Squad.
United’s interest has cooled in recent weeks but if Carvalho is given the chance to impress in Brazil, then that may push Van Gaal and Woodward into action.

A legend for Juventus and a crucial member of a thrilling Chile side, Vidal could move away from Italy this summer.
The Italian Champions are reportedly considering selling Vidal in order to fund moves for other players and a good World Cup will put him right at the front of the shop window, if he wasn’t there already.
For his club, he has scored 28 goals in 95 league matches, highlighting him as one of the best goal scoring midfielders around at the moment.
Despite Chile’s manager enjoying implementing a variety of tactics, Vidal’s role has always remained the same since his first cap against Venezuela.
His skill set will be a fantastic tool to have for any team but with United suffering in midfield in recent years, signing someone of Vidal’s calibre would be a huge coup.
