Paul Scholes says that new manager Louis van Gaal will improve Manchester United by 25%, when he takes over after the Netherlands' World Cup campaign.

Van Gaal has guided the Dutch team to the semi-finals of the World Cup and will have a shot at getting their hands on the prestigious trophy if they can defeat Argentina on Wednesday.

Scholes has heaped praise on the Holland manager for the way he has taken the team to the brink of the finals, and says everyone at Old Trafford is waiting for him to take charge.

"Right now, Manchester United fans and myself cannot wait for Louis van Gaal to get the job started at Old Trafford. It's not a vintage Holland team he's managing and Van Gaal has got them to the brink of a World Cup final. He's going to have to perform a similar operation at United after a shocking season in 2013-2014," Scholes said, as quoted in the Guardian

United had a season to forget under David Moyes, which saw them finish seventh in the league and failed to qualify for Europe for the first time in 24 years. The former England international feels that the former Bayern Munich manager can bring his vast experiences in club football and improve United and bring them back to winning ways.

"Van Gaal seems to have the Midas touch, and with his coaching reputation and vast experience he can bring a lot to the club. He'll improve last year's performance by 20/25%, I feel," Scholes explained.

Scholes is also hoping van Gaal will bring in a few more players in addition to the two big money signings Ander Herrera and Luke Shaw. He also feels the manager can also bring out the best from the players already at the club.

The Red Devils legend praised the Dutchman's courage in taking key decisions and his tactical genius in guiding Netherlands to the semi-finals of the World Cup.

"As well as the new signings, Luke Shaw and Ander Herrera, and hopefully more to come, he'll bring more out of the players who are already there. I'm actually really excited about next season.

"Van Gaal is not afraid of big decisions, which he showed by bringing on the Newcastle keeper Tim Krul for the Dutch No1, Jasper Cillessen, for the penalty shootout against Costa Rica [in the quarter-final]. Krul had saved only two out of the last 20 penalties with Newcastle. The evidence did not seem to be there for that big a decision," the former Red Devils midfielder added.

"But whatever Louis van Gaal does, seems to work. He substituted his captain, Robin van Persie, when Holland were 1-0 down to Mexico and they came back to win. He seems to have a bit of genius about him, and hopefully can work this magic on United next year," Scholes concluded.
