Louis van Gaal was often criticised for his boring and rigid play-style last season, but many of the players have confirmed they have had more attacking freedom since the Portuguese boss took over in May.
Shaw made his Premier League return for Man United last week against Bournemouth and will undoubtedly be looking forward to facing his former club Southampton on Friday.
Speaking about his role, Shaw insists full-backs now have the license to go forward.
“At times people have said maybe he [Mourinho] doesn’t like his full-backs to go forward but that’s not the case,” he said.
“He gives both full-backs that license to go forward, obviously not at the same time but if I have the chance then it’s up to me if I want to go forward or not.
“It’s not that I’ve got to stay put or do particular things, I’ve got the freedom to play and that only gives me the confidence in what I want to do to help the team.
“I was at Southampton for a great ten years and I’m really looking forward to seeing some of my team-mates that I played with.”
Shaw joined from Saints in 2014 and although many believed he wouldn’t be able to re-find his impressive form prior to his injury last season, it looks like he has started exactly where he left off.
The Bournemouth fixture was his first league appearance since September, but his impressive performance suggested different.
It’s brilliant to finally have him back on the pitch and Mourinho will be happy to have his services available ahead of the new season.
