Germany meet Spain in tonight's Euros quarterfinal with Barcelona teen Lamine Yamal and Athletic Bilbao' Nico Williams in excellent form.
Nagelsmann said of 16 year-old Yamal: “He has great talent. I don’t think there are many that good at his age. He is very well surrounded. He can beat a player both ways – he’s excellent, a lot of fun to watch.
"But it’s also true that he lacks experience, and that doesn’t mean that we’re going to give him regular chances. Facing him is a good test for our players.”
He continued: “I don’t solely focus on their wingers. Spain has many qualities, not only the wingers. They are a complex team to defend.
“We need the ball, that’s for sure. It’s always easier to play against a team that wants to have the ball if you have the ball yourself.”
