Louis van Gaal will sit down with his players after their tour and tell them whether they have a future at Manchester United.
Van Gaal and his 25-man squad fly back to Manchester in the early hours of Tuesday morning following their final game of the US tour against Liverpool.
Van Gaal has racked up morale-boosting wins over the Los Angeles Galaxy, Roma, Inter Milan and Real Madrid, but he is still unhappy with certain aspects of his squad.
Javier Hernandez, Shinji Kagawa and Wilfried Zaha face uncertain futures after limited playing time in America while Marouane Fellaini and Anderson, who have not made the trip, could also be shown the door.
Van Gaal wants to tell his players whether they have made the cut well before the transfer window closes so he will approach them individually and inform them of their fate when they get back to England.
"I shall make judgements after the tour," the United boss said.
"I have let all the players play so I know now more than I did before.
"But in football you have to judge. Always you have to give a chance to a player to make a transfer when you see that his perspective is not so high to play.
Manchester United: Potential summer transfer targets
Manchester United: Potential summer transfer targets
1/19 Arturo Vidal
The Juventus midfielder is among United's top targets this summer, particularly after impressing for Chile at the World Cup. Having helped his current team secure the Serie A title, Juventus aren't keen on letting him go.
2/19 Marco Reus
Rumoured to be near the top of United's target list, a possible swap deal involving cash and Shinji Kagawa has been mentioned. The Borussia Dortmund player would not be a cheap acquisition, especially given his recent declaration that he wants to stay at Dortmund next season
3/19 Arda Turan
Former manager David Moyes had been seen watching Turan, though his dismissal put a doubt over whether United were still interested. The winger's agent claims an offer has been made, so is the Atletico Madrid winger on his way to Old Trafford?
4/19 Arjen Robben
The Bayern Munich winger has said Van Gaal has offered him a place at Old Trafford if he wants it. Currently he's happy to stay where he is, but things can quickly change.
5/19 Claudio Marchisio
With Paul Pogba highly unlikely to be prised away from Juventus, United's attention could turn to team-mate Claudio Marchisio. The Italian international would provide some class and experience.
6/19 Mats Hummels
With defensive reinforcements high on United's list of priorities, Borussia Dortmund's Mats Hummels has unsurprisingly been linked with a move to Old Trafford. The German has been earmarked as the ideal replacement for the now-departed Rio Ferdinand and after his impressive showing at the World Cup, he's even more desirable.
7/19 Raphael Varane
Raphael Varane has already snubbed United once in his career, opting instead to join Real Madrid. It would surely take a big offer to prise the classy defender away now.
8/19 Seamus Coleman
Reportedly already the subject of a £15m bid, Seamus Coleman could be the man being lined up as the answer to United's problems at right-back.
9/19 William Carvalho
The Sporting Lisbon midfielder has reportedly been watched 15 times by Manchester United, although the £29m asking price could prove a stumbling block. The Portugal international has also been linked with Arsenal.
10/19 Xherdan Shaqiri
Bayern Munich winger Xherdan Shaqiri has struggled to force his way into the first team at the Allianz Arena and could be a target for United as well as rivals Liverpool. His impressive displays for Switzerland this summer could make it harder to prise him away.
11/19 Alex Song
Barcelona are understood to be ready to let the former Arsenal player leave this summer. Could provide some strength to United's midfield. Could also bring embarrassment judging by his behaviour at the World Cup.
12/19 Fabio Coentrao
Supposedly came within hours of signing in January, the Portuguese left back could be brought in to provide back-up to Luke Shaw.
13/19 Julian Draxler
A long time Arsenal target, United are reportedly interested in pinching the young German with a bumper offer. Seems unlikely though. Arsenal also strongly interested.
14/19 Sami Khedira
The Germany international is reportedly being pursued by a host of sides, and United might be wise to get in the mix as they look to add some quality to a fairly feeble looking midfield. Real Madrid appear open to letting him go with the 27-year-old having just one year left on his contract. Arsenal and Chelsea are among the others keen on signing the World Cup winner.
15/19 Edinson Cavani
The Uruguayan hitman would prove pricey and tricky to snatch away from PSG and it seems unlikely United have enough to offer him.
16/19 Luciano Vietto
The Racing Club youngster has been impressing in Argentina for some time although a move directly to United would be something of a surprise.
17/19 Santiago Arias
Should a move for Seamus Coleman fail, PSV defender Arias is reportedly being lined up by United. Played for Colombia throughout the group stage of the World Cup.
18/19 Miralem Pjanic
Rumoured to part of a joint bid including teammate Benatia, the Bosnian midfielder is reportedly another on United's large hit list.
19/19 Kevin Strootman
Van Gaal knows Strootman well from working with him in the Netherlands set-up and has indicated he is interested. Roma are reluctant to sell whilst his recovery from a knee injury may prove a stumbling block.
"You have to say it in advance. When you say it on August 31st it's too late. I shall say to the players what I think after the tour."
Van Gaal has sent coach Marcel Bout back to England to work with the likes of Robin van Persie, Adnan Januzaj, and Fellaini, who have been given time off following their exploits at the World Cup.
"They (Van Persie, Fellaini and Januzaj) have already trained. I sent Marcel Bout back to train them, along with Nicky Butt," Van Gaal said.
Van Gaal thinks Van Persie is unlikely to be fit to face Swansea on August 16, but the other two could be in contention for United's Barclays Premier League opener, depending on how they react to training.
"I have to look at Robin van Persie if he is coming back or not," said Van Gaal, who coached the striker at the World Cup.
"But if you have three weeks holiday and only four days training before the Valencia friendly (on August 12) you are not fit enough.
"For the first game in the Premier League it's possible but I don't think so."
United's money-spinning tour of the US started amid a blaze of publicity in Los Angeles, but two-and-a-half weeks later, their presence in the US is a lot more low-key.
Only a couple of hundred invited guests turned up at the Sun Life Stadium to watch United's final training session in America.
The session was more of a warm-down as they only played Real Madrid on Saturday night.
On the eve of the match, Liverpool manager Brendan Rodgers said Van Gaal is facing a totally different challenge to any other he has faced in his long and successful career.
Van Gaal, who has won titles in Spain, Holland and Germany, says he is up to the challenge.
"That's why I'm here," he said.
"Maybe he is right because I have to experience that but I was also in Spain and in my first year I won three titles, in Germany I won two titles.
"If I win one here we will all be happy."
Van Gaal is expected to ring the changes for the final in Miami, which kicks off at 1am BST on Tuesday.
The winner takes home a prize of one million US dollars (£600,000).
