Asked about what he will offer the Red Devils, Telles told the club's website: "I like to think of myself as a very intelligent player, a set-piece specialist and I'm always looking for opportunities to create passes to score goals.
"I'm in the best moment of my life in terms of being a versatile player, and obviously coming to play in the Premier League and playing against the opponents I have done already, and playing in a league as strong as the Premier League. I hope to be able to bring my best to the club.
"I look at being a defender in a different way with my goals. I'm looking to create more openings wherever possible but during training I also pay particular attention to set-piece training. Apart from the key basics of being a defender, which is obviously about defending well, I want to have extra aspects to my game so I'm a versatile player.
"I have great beliefs in my defensive capabilities but also in my attacking ability. I'm in the best moment of my career and I believe I've grown a lot, and hopefully I can continue to do so."
