Man Utd believes that Ole Gunnar Solskjaer has transformed the attack without requiring significant transfers

Ole Gunnar Solskjaer is convinced that he has already added factor X to the Manchester United attack – even before finishing his summer reconstruction.

The Norwegian intends to oversee a change in the club's style of play after the much-criticized reigns of Louis van Gaal and Jose Mourinho.

The key to this will be an energetic forward-thinking approach, more in tune with the tactics employed by Pep Guardiola and Jurgen Klopp in Manchester City and Liverpool.

Solskjaer intends to build his attack around the speed of Marcus Rashford, Anthony Martial and new rookie Daniel James – promising to get the fans out of their seats.

He submitted his players to rigorous double training here in Perth to make sure that the alarming weakening of last season's end, which had seen them win one of their last nine games, does not happen again. And the signatures of James and Aaron Wan-Bissaka's electric beats were designed to give speed to a team that looked so painful compared to its Premier League rivals in the last six years.

"Both have maximum speed," said Solskjaer. "Modern football, it's stop-start, it's gone, speed, tempo, quality, so these two have put their mark." Of course, with our boys, we have some fast ones.

"The more factors you have in a team, the better you are. Any player who plays against, for example, Rashford, Martial, Dan James, with the rhythm he's got, I think you fear he's hurting you even if they have a day off. "

Solskjaer plans to add at least two more signatures this summer, with Harry Maguire and Sean Longstaff as main targets.

But in addition to recruiting new recruits, he is determined to improve the inherited Mourinho players, with levels of fitness that he is most determined to tackle.

United has been the subject of harsh criticism over the past few seasons for its inability to play high energy football that has been so successful for City and Liverpool in particular.

Solskjaer paid the price as the season has pbaded since the last quarter, following the dramatic rebound that accompanied his appointment as interim caretaker in December.

A run of 14 wins in 17 games was undermined by the ensuing collapse, preventing United from qualifying for the Champions League for the third time in six years.

But the manager of United is convinced that the benefits will be felt after their pre-season work.

"They should feel tired, they should feel they are getting something out of it," he told the club's website. "We build fitness, robustness, mental toughness and that has been very encouraging. They were great.

"Of course, we've also been working on two new tactical approaches and ways that we think could be useful this year.

"You want to get everyone going and you want to get there without wasting your time and losing three or four days.

"I was part of it myself when the pre-seasons are stopped and started, you do not make your pace. But the season is long and if you have these six weeks, then the league starts and there are still three or four weeks where we only have one game a week, so we can also do a good job. So, let's see.

"I'm sure when the league starts, we'll be ready, fit and fit enough."

Despite Solskjaer's willingness to join emerging UK players James, Wan-Bissaka and Longstaff, he insists he will not limit his activity to national targets.

He added: "It does not matter that they are English, Norwegian, French, Brazilian, you just want good players, good people, quality and speed, of course, it's a great thing in football today. "
