The former Southampton star has endured a difficult first season at Old Trafford, but the backing of his manager has left him positive about the future.
It has been a difficult first season for Shaw at United following his big-money move from Southampton in the summer, with injuries hampering him throughout the campaign.
A further setback has been the tinkering of Dutchman Van Gaal, who was persistently changing his formation at the beginning of the season and often opted to select countryman Daley Blind ahead of Shaw on the left of his defensive unit.
However, the United manager has recently backed the defender to MUTV, and Shaw says he is delighted to have heard such kind words from his boss.
"I was really happy when I saw the manager had said that about me," he said.
"Just to know he’s got trust in me is something special and I couldn’t ask for any more."
Shaw was forced to leave the field in last weekend’s 2-1 win at Crystal Palace, a result which made it all-but certain that United will be returning to the Champions League next season after a year-long absence.
That was always the aim for manager Van Gaal, and he appears to have succeeded in that mission. For Shaw in particular, it is an exciting prospect to be playing in Europe’s elite competition at just 19 years of age.
"As a 19-year-old boy, to be able to think that you’ll be playing in the Champions League next season is really incredible," he added.
"It’s something that I want to achieve but not just me, everyone else in the squad wants to achieve it too. It’s one of the biggest competitions in world and we all want to show what we can do on the big stage."
