While insisting his game continues to improve, Gravenberch has spoken of the difficulties he has experienced in recent months.
"Still going strong, but to be honest it's really tough as well," he said. "Last season I didn't play a lot and now I played almost every single game. It's tough but I still keep going.
"My game has developed a lot this season. At the beginning of the new season I had to adapt to the new position, I didn't play a lot there (beforehand) but now I know what I have to do. The manager also fully trusted me there so I'm really happy with that.
"When you play there you receive a lot of balls and that's what I needed, to be in my comfort (zone) and break through the lines and open up in the play.
"Last season my role was an eight, sometimes a 10. Then the manager came in and I had a conversation with him, he wanted to try me as a six. I felt the trust from him and we've played 33 games and he's put me in for all 33, so that's a lot of trust!
"Now I don't get the ball as much, they (opponents) know how we play and they want to close the middle. It makes it a little bit difficult for me but I have to find the way through. That's what I do."
