Jose Mourinho believes Luke Shaw's resurgence deserves to be rewarded with a new long-term deal at Manchester United .
Just a few months ago time appeared to be up on the 22-year-old's Old Trafford career.
Sidelined by a double leg break in September 2015, Shaw struggled to win over Mourinho during the Portuguese's first campaign in charge.
Those issues continued after recovering from a foot complaint this term, but the England international has kicked on since making his first start of the campaign in December.
The triggering of the one-year extension clause in Shaw's contract means he is committed until the end of the 2018-19 season, but Mourinho would like him to stay longer.
"With Luke it is not about changing my mind," Mourinho said. "With Luke, it's just the evolution or no evolution of his potential.
"Like I think you say, fulfil the potential. It's just about that.
"Because I know Shaw since he arrived in the Premier League with Southampton and I know his potential and his quality.
"Could he come in my direction, in the way I think football , the way I like my players to be not just on the pitch but also during the training week? And he made a big effort.
"He's now for a few months free of these minor injuries that sometimes stop evolution and I'm really happy, so I think the natural consequence of it is that he will have his contract and he will be a Manchester United player for years."
