FC Midtjylland winger Pione Sisto feels he can do more at the U21 Euros.
Sisto's Denmark was thrashed by Germany on the weekend.
"It was definitely the best team I've played against, so it was great to test myself against the best," he said.
Sisto is being watched by Everton and Manchester City while in the Czech Republic.
"I learned that top games go really fast, and it's also faster than I have ever experienced. I have ambitions to one day reach that level."
