Louis van Gaal has won his battle to shorten Manchester United summer’s tour next year, with the new manager branding the demands of travelling long distances in America during the current visit as “dreadful” as he attempts to ready the team for the new season.

The Dutchman is clear that United’s commercial demands must be rolled back to give him the best chance of ensuring the side’s success.

Speaking at Pasadena’s Rose Bowl, where Van Gaal was nearly half an hour late for the press conference due to the heavy traffic that gridlocked the 30-mile drive from the team hotel in Los Angeles, he said: “The tour was already arranged [before he became manager] and I shall adapt and United will do everything to apply to my rules but I have said that already. This is the first time I am late for a press conference, but it is the Los Angeles traffic, so I am sorry for that.”

United have to repeat the four-hour round trip again on Wednesday evening when they play Los Angeles Galaxy at the Rose Bowl, and the club have at least three more matches, in Denver, Washington and Detroit. There will be a fourth if United reach the final of the International Champions Cup, in Miami on 4 August.

Asked about next summer’s tour, of which the destination is yet to be decided, the 62-year-old said club executives had agreed with his demand to curtail its length. "Yes, I hope that [it will be shorter], but they have already said that to me and I am very confident that it shall be,” he said.

Van Gaal is insistent that commercial demands are proving a difficulty as he attempts to make United challengers again after finishing in a dismal seventh under David Moyes last season. “More or less. We have to prepare the season and when you have commercial activities and dreadful distances, having to fly a lot and the jet lag, it is not positive for a good preparation,” he said.

Van Gaal, whose players had an open training session at the Rose Bowl on Tuesday evening, is so far pleased with how the squad is working under him. “I have to say that is has been fantastic. Maybe you think that every trainer-coach will say that when they are new, but I mean it. The players are very anxious to do what I say and follow the instruction of my assistants.

“The focus of what I have seen in training sessions is top level, but we have to see if the performances are also top level.”

United’s summer signings, Luke Shaw and Ander Herrera are set to make their debuts against the Galaxy. Shaw, who will replace Patrice Evra as the first-choice left-back, said: “I don’t feel any pressure to come in for Evra, he has been great for the club for 10 years, so hopefully I can carry that on. There will always be pressure, but I try not to focus on that, just on my own game on the pitch. With the new gaffer, you have to impress in training and that is what I am looking to do. Personally I think United is the biggest club in the world and the one that will push me to my best and improve my game as long as I am here.”

Herrera said: “I can promise to work hard and be a good professional, but there are other midfielders in the team. Between all the players, I am sure we will help the team, but not only me. There are a lot of midfielders and they can play well like me.”
