Doughty was told by Ramsey that he needed to work on his fitness towards the back end of last season, and the youngster took his manager's advice on board, doubling his efforts to make sure he was ready for the new campaign.
His improved fitness has now astounded Ramsey, who has rewarded Doughty with six appearances already this season.
“I don’t know what he’s done over the summer, but his transformation has been incredible," he said.
“It’s easy to go off in the summer and enjoy yourself, so his dedication and commitment has been superb and it’s been noticed by a lot of people at the club.
“He’s been at the top in all the fitness tests we’ve done so far. For a young man to do what he’s done and in the way he’s done it has been nothing short of outstanding. Most youngsters at our club should be looking up to him and thinking to themselves ‘if he can do it, I can do it too’.”
Doughty came into QPR's first-team towards the end of the 2014/15 campaign, where he made three Premier League appearances.
He has now established a place for himself in the senior squad, and if he continues to progress at such a rapid rate, then Ramsey could have an extremely bright prospect on his hands.
The R's are keen to develop their own youngsters, and are working hard to reduce the average age of the squad - after pilling it up with experienced players during their recent spells in the Premier League.
It seems that Doughty is leading the way for their youth team graduates, and Ramsey will hope that more prospects follow his lead in the years ahead.
