After signing Fred from Shakhtar Donetsk, Manchester United have been quick to make their second aquisition of the summer.
Dalot joins the Red Devils from Porto and has put pen-to-paper on a five-year deal.
Manager Jose Mourinho has hailed the right-back as as a talented young player.
“Diogo is an extremely talented young defender with all the qualities to quickly become a great player for this club,” he said.
“He has all the attributes that a fullback needs: physicality, tactical intelligence and technical quality, combined with a Porto Academy mentality which prepares players for the maturity they need at the professional level.”

You came through the system at Porto, another big club with great traditions, so what has that taught you?
I grew up at Porto. Porto gave me everything. Who I am today is because of what Porto gave to me and that has been most important.
You only made your league debut in February, but youâ€™ve got a wealth of experience at youth level particularly, so what did it feel like to win the Under-17 European Championship?
I think that the European Championships was when I realised that I could do great things in football and, since then, Iâ€™ve been improving a lot and I hope to improve more.
How proud do you feel to be Jose Mourinhoâ€™s first Portuguese signing with United?
Yeah, itâ€™s very good. It was very important to make this choice and I hope to help him, because I know that he will help me to improve a lot.
Youâ€™re still a teenager, but does the move show how much faith the manager has in your potential to recruit you at this early age?
Yeah, I think that age is not very important now in football. I think that if you work and you improve, I think you can handle it.
How would you describe yourself as a player?
Like a hard-working player, I think. Iâ€™m very instant in improving and Iâ€™m mostly a hard-working player, I think.
Can you play at left-back as well as at right-back?
Yeah, I prefer to play at right-back, but if I need to play in any position, I will play, no problem.
The Premier League will be new to you. Youâ€™ve already played at Anfield though, against Liverpool, helping to keep a clean sheet by the way, so what was the experience like and are you aware of the rivalry weâ€™ve got with Liverpool?
Yeah, it was unbelievable, my debut in the Champions League. Just feeling the weather, the Champions League, the song of the Champions League, it was very good.
How excited are you for the challenge of Premier League football?
Iâ€™m very excited. For me, it is one of the biggest leagues in the world and Iâ€™m excited to play there.
What are your short-term plans and ambitions and your long-term goals here at United?
Just to help the club achieve good things here and win, because this is a winning team.
The summer tour could provide you with a chance to get to know your team-mates, to play for Manchester United as well, so how much are you looking forward to it?
Very. Iâ€™m looking forward to meeting my colleagues, to meet the staff, to meet every person and to hopefully help in some way.
Do youÂ haveÂ a message for all the Manchester United fans, watching this throughout the world?
Just expect that I will give everything for this club, for this shirt and, hopefully, help the club to win. Thatâ€™s the most important thing.
