So three games, three wins. Not bad for Louis van Gaal and his boys with just Paris Saint-Germain (PSG) left to face on June 29th. But is this impressive form going to transfer over to the Premier League next season and win them the league?
Wayne Rooney was on the mark for his first goal of the tour along with promising youngsters, Jesse Lingard and Adnan Januzaj against Barcelona.
United have looked comfortable on their US tour but the Premier League is a different beast. Games span across nine months and 38 games is a long time to keep up impressive form.

Of course, United are no strangers to challenging for the title but the team has changed dramatically since their last title win in 2013.
Have Louis van Gaal's men got enough to give them the edge over Chelsea, Arsenal and Manchester City next season?
It's no secret that United have splashed the cash in this transfer window, bringing in four new signings to add to last season's transfers.
It's clear Van Gaal is building a new team that will aim to dominate English football once more.
With the purchases made this summer, it looks as though he has bought some key players in the areas that were lacking last season and in David Moyes period at the club.
Duo Bastian Schweinsteiger and Morgan Schneiderlin bring a presence of box-to-box midfielders back to United that has been lacking for some time.
They will have good vision and a battling mentality like the days of Paul Scholes and Roy Keane, whilst also bringing their own individual talents to the side as they have displayed at Bayern Munich and Southampton.
Although Van Gaal criticised Schweinsteiger for his performance against San Jose Earthquakes, and Schneiderlin struggled a little against Barcelona, these two acquisitions should come good in the coming weeks.
Exciting youngster Memphis Depay will add more pace and flair around the 18-yard box as he looks to make things happen, glimpses he has shown in the last few weeks.
Matteo Darmian will also bring a strong, experienced head to the United back line to help plug some of the leaks of last season. United are of course still concerned about their back line as being their main weakness, which has been tested at times on the tour, hence their pursuit of Real Madrid defender, Sergio Ramos.
With these bedded in with the established United stars, United look like a force to be reckoned with.
We've saw some interesting tactics from Van Gaal last season, as he changed from 3-5-2 and 4-5-1 formations to 4-4-2, and then back again. The wing back system worked well in some games, in others not so effectively. Radamel Falcao’s presence was not as impacting as the manager would have hoped and other stars didn't quite click in their position to maximise their potential in big games.
But looking at the pre-season tour will surely restore United fans hopes of a successful campaign. Rooney’s lone striker role seems to work well, with the likes of Depay supporting him. Although he's only scored the one goal, United’s attacking threat looks dangerously good.
Again, another pleasing thing for United fans to see.
A PROMISING WINNING MENTALITY
Put simply, United are winning again, and winning playing attacking football.
Last season, United looked clunky in some of their play, their passing was sloppy and they sometimes lacked enough creativity to produce an array of chances that we've all been used to seeing over the Premier League years.
Sam Allardyce had accused them of long ball tactics, an unthinkable link to put to a Manchester United side who are known for good attacking football, when his West Ham United team met United at the Boleyn Ground.
This was a comment not well taken by Van Gaal, as explained in The Daily Mail, who provided his own analysis of the game to prove his team were the better side and only commenced with long balls when target man Marouane Fellaini was brought on from the subs bench.
Now that has changed from viewing this tour. United are playing slick moves around teams, the players look like they are enjoying their football again and everything seems to point towards a revival of success.
CAN THEY WIN THE PREMIER LEAGUE?
On the U.S. tour viewing, it would appear United are much improved from the fourth place side last season, but they need to tighten up at the back if they want consistent results against the top four.
With their attacking force, the likelihood of them being serious challengers for the title next season are looking very promising indeed.
What do you think? Can United win it?
