With Louis van Gaal finally finishing his duties as Netherland's manager, he will now step right into the role of leading Manchester United. The new boss also stated that only the places of David De Gea, Juan Mata, Wayne Rooney, and Robin van Persie were safe as he prepares to build for the future.

Since the World Cup has ended, we take a look at SIX players whose career seems to have been affected by their performance on the world stage. Based on how they did, Van Gaal may need to cash in on some of the players in order to fund new moves as competition for places in the Red Devil's squad are currently up for grabs.

Shinji Kagawa (Japan – Attacking Midfield/Winger)

KagawaJAP

After Japan’s early knockout from the World Cup, Shinji Kagawa’s place at Manchester United is under huge threat. The midfielder was hardly given any playing time in the previous season and with his recent showing in Brazil, he could once again find himself on the bench.

His showing for his national squad didn’t provide Louis van Gaal with any proof he has what it takes to make it into his new manager’s game plan. Kagawa had a lot of playing time but failed to leave a mark after seeing his side lose two and draw one of their three group matches.

Nani (Portugal - Winger)

NaniPOR

Nani has been heavily linked with a move away from Manchester United ever since the end of the previous season. Louis van Gaal is believed to want to use Juventus’ interest in the player to lure top target Arturo Vidal to the club. Although he scored a cool finish against the USA, he was unable to step up on the world stage when Cristaino Ronaldo didn’t seem to be at his best.

The fact Van Gaal is willing to use the Portoguese as part a swap deal proves his Old Trafford days are limited. He has produced some top notch displays in the past, but has failed to live up to his potential on most occasions. If he is the key to Vidal’s move, expect Nani to part ways.

Marouane Fellaini (Belgium – Central/Attacking Midfield)

FellainiBEL

Despite receiving a lot of criticism in a Manchester United shirt, Marouane Fellaini was a completely different player when representing Belgium at the World Cup. He wasn’t named in the starting line up in his nation’s opener against Algeria, but came on to score a vital equalizer before his side eventually won 2-1.

The next four matches saw him be named in the starting line up while producing some outstanding displays for his team; therefore Louis van Gaal should really consider playing him at a more advance position than that of his usual defensive midfield role at Old Trafford before deciding to sell him.

Antonio Valencia (Ecuador - Winger)

ValenciaECA

Antonio Valencia didn’t have the best build up to the World Cup when he picked up a red card in a friendly against England before receiving another sending off against France in the group stages. Despite being the captain of his nation, his discipline wasn’t that of a leader while also failing to reproduce outstanding Premier League form from two seasons ago.

Good news is that Louis van Gaal still values the likes of Valencia after the player recently extending in Manchester United contract. However, the Dutch boss is still on the lookout for another winger, with Angel Di Maria a prime candidate. He may still be at Old Trafford next season, but his starting place is under huge threat.

Patrice Evra (France – Left Back)

EvraFR

With Patrice Evra’s potential move to Italy put on hold after Antonio Conte’s departure as Juventus coach, he could very well continue to play out his contract at Manchester United. He is the first choice left back for the French national team and has always been a player who can aid the attack as well as track back to continue his defensive work.

Evra provided one assist from his four World Cup matches and is seen by Louis van Gaal as someone who has bags of experience. With the arrival of 19-year-old Luke Shaw, he can be seen as the perfect role model for the young star.

Javier Hernandez (Mexico – Striker)

HernandezMex

Javier Hernandez was desperate for a larger Manchester United first team role and has been linked with a move away from the club in recent months. Although he managed to net one goal at the World Cup, he didn't get to start any of his four matches as he once again, was being deployed as a substitute.

Since he was unable to prove himself to Louis van Gaal, his role in the United squad will probably be no different from the previous seasons. With a majority of teams interested in his services, there is a high chance that he could leave in search of first team football.
