The Portuguese has one United appearance under his belt since joining from Sporting Lisbon last month.
But he is already impressing teammates with how well he has settled in.
"Perfectly. I mean, it is like he has been here for two years already," the full-back told the club's website during their warm-weather camp in Marbella.
"He is getting on very well with the lads, it is very good to have him here, it is very good for me, very good for the team, he is a fantastic player and a fantastic person.
"So, it is one more to help the team."
