In an interview with Sky Sports, Ruben Diaz’s youth training coach Joao Trao said that Diaz is a special genius and he can fill the vacancy left by Kompany.
鲁本·迪亚兹（Ruben Diaz）的青年训练教练若昂·特拉（Joao Trao）在接受《天空体育》采访时说，迪亚兹是一个特别的天才，他可以填补空帕尼留下的空缺。
Trao said: "Dias was once my captain, he is also the captain of each of our age groups, he is a natural leader, he likes to lead the team, he also knows how to lead the team, he knows how to play The locker room speaks for the coach."
"When he integrates into Manchester City, you will see this, he will show his leadership qualities, which can help the team to complete the task outstandingly."
"Not only can he lead the team by shouting loudly, but he can also tell the players how to play according to the coach's ideas."
"His defensive ability is very comprehensive. He can complete the task well whether he presses forward or shrinks the defense. He is good at handling the ball and can find the right time to pass the ball. He can adapt to Manchester City's play very quickly."
"Leaving Benfica is not easy for him. He has been playing here for many years, but on the other hand, joining a club like Manchester City is a challenge. He is also excited about it. He is very positive in my impression. It is a role model for every young person, whether on the court, in training or off the court."
"From the time he joined Benfica's youth training, I knew he would be successful. During the period of working with him in the U18, I am sure that he will become a top player. He is very special."
