Manchester United owners the Glazer family have explained how Louis van Gaal's pedigree as one of the most successful managers in the game persuaded them to appoint the Netherlands boss to replace David Moyes.

Van Gaal was appointed on Monday on a three-year contract and will officially take charge of United after the summer's World Cup finals in Brazil.

The 62 year old has won league titles in three different countries with Ajax, Barcelona and Bayern Munich while he claimed the Champions League during his spell in the Dutch capital.

And after Moyes was appointed last summer having never won a major honour, the Glazer family have revealed Van Gaal's arrival at United was motivated by his track-record.

Joel Glazer said: "I am delighted that Louis will be our next manager. He has an outstanding pedigree as a coach, both as a man who motivates his teams to win trophies and as someone who believes in giving young players a chance to prove their worth. I am sure he will make a big impression on the club, the players and the fans."

Avie Glazer added: "Louis joins us at an exciting time and has already communicated some great ideas for how the club can move forward. The board is right behind him in his plans and everyone here is already looking forward to the start of next season."

Van Gaal will not be unveiled as United manager until after the World Cup, where Netherlands face Spain, Chile and Australia in Group B ahead of the knock-out phase.

United suffered their worst ever Premier League finish during Moyes' tenure and failed to qualify for the Champions League and executive vice-chairman Ed Woodward says the Dutch boss can return the club to their former glory.

"In Louis van Gaal, we have secured the services of one of the outstanding managers in the game today," Woodward said. "He has achieved many things in his career to date and Old Trafford provides him with a fitting stage on which to write new chapters in the Manchester United story.

"Everyone is very excited about this new phase in the club's history. His track record of success in winning leagues and cups across Europe throughout his career makes him the perfect choice for us.

"People know him as a larger than life character but I have also been extremely impressed by his intelligence, thoughtful approach to the role and his diligence. I'm looking forward to working with him."
