Ole has praised Maguire ahead of the new season.
“I’m delighted we have got Harry in because he’s going to be great for this club,” Solskjaer said.
“He was always my number one target. I more or less made my mind up when we played Leicester that if it was possible to get him, we should at least try. He is so composed on the ball and he gives the team another dimension.
“He has already shown what a presence he will be and what an impact he will have in the squad. Harry is a leader, an established international, a goal threat and a very, very good defender.
“I don’t want to compare us to Liverpool or Harry to Van Dijk, but I know Harry is going to have a massive impact on us, yes.”
As for inducting youngsters into the team, Ole sounded confident.
“You can call it a gamble. I am just staying true to what I believe in,” he said. “I believe in this way of managing a football club.
“I am paid to manage for the club and it is not just about me getting results now to get my reputation. It is about the club going forward in the right direction.
“If we don’t make these decisions now, they will have to be done in 12 months or 18 months or 24 months because at some point these kids will have to be a part of Man United. That has always been the case.
“That is the upside and downside of who you want to keep. For us, to give our kids the best chance, we decided this is the right way.”
