Jones has been a revelation since swapping Ewood Park for Old Trafford this summer and Dahlin is backing the former Rovers man to continue his rise.
"I've seen Phil Jones - who obviously used to play for my old club Blackburn - and he's a huge talent," Dahlin told the Sunday Mirror.
"I really believe he has a massive future.
"A lot of people wondered why United paid so much for him - and it was a lot of money - but I really think he has everything.
"He will be England captain in a couple of years, that's how good he is."
