The Roma manager is a long-time admirer of the Portuguese defender having signed him for United from Porto in 2018.
Italian publication Calcio Mercato had reported that Roma director Tiago Pinto made contact with Dalot’s agent and that there had been an ‘agreement in principle’ for the move to go ahead in January.

Roma manager Jose Mourinho had been keen to reunite with Dalot who he signed for United in 2018
However, recent changes at Old Trafford have appeared to scupper Mourinho’s plans.
Upon discovering Dalot’s reported plans to leave next month, the German manager has now blocked a move.
Dalot’s intentions to leave the club come as no surprise seeing how little he was used by former United manager Ole Gunnar Solskjaer.
When the Norwegian was in charge, Dalot made just three Premier League appearances this season – with a total of 84 minutes played.
Dalot had struggled for game-time under Ole Gunnar Solskjaer who often chose Aaron Wan-Bissaka at right-back
There has been a change however in recent games, with Dalot starting ahead of Aaron Wan-Bissaka and lasting the full duration in wins over Arsenal, Crystal Palace and Norwich.
If Dalot continued to impress, he could now establish himself as the club’s first choice right-back.
The news comes as a blow to Mourinho, with his sixth-placed side now expected to look elsewhere for a full-back.

After Rangnick’s first game in charge against Crystal Palace, Dalot said: ‘It’s difficult to change and have an opinion in such a few days, but we’re going to have time to know him and he’s going to have time to know [us] as well for the next couple of weeks.
‘I’m sure that if everybody’s together, everybody’s into it, we’re going to do a fantastic job. We’re going to help him and he’s going to help us as well.
‘There’s no secret that he’s a very good manager with very good ideas to play football. Hopefully, we can help them to give us the best that he can give as well and vice versa.’
