Ajax midfielder Davy Klaassen admits he wasn't prepared for his original move to Everton.

Klaassen struggled for his season in England before leaving for Germany to rebuild his career.

He recalled: "At Everton, the footballing aspect was also the starting point at first, but if you don't run twice as hard, the ball just goes up in the air and it happens in a different way.

"In the beginning I really thought: Yes, but guys, we can still play football and with power? But the rest thought otherwise, and as a player you just have to let it go.

"I really learned that in England, the different way of experiencing how to achieve a result, and it helped me a lot in Germany."
