Everyone within the club can confirm that," Proper said.
Schreuder has emphasized the need for squad depth as NEC prepares for an extended fixture list including both Eredivisie and European matches.
"But I don't want to be a 12th, 13th, or 14th man at all. Actually, I just want to be on that pitch every match.
As one of the eleven," Proper said. "The guys did great, even when I played at the start of the season.
And everyone played a role in the success."
Despite understanding why his competitors gained favor, Proper maintains his ambition remains unchanged.
"Somewhere I can understand it. Players in my position have done well.
But it would be strange if you didn't say that you think you should always play, in my opinion," Proper said.
With the transfer window open for another month, the midfielder has held preliminary discussions regarding his prospects.
"This is my club. I've played here for so long.
You just want to join in the current great success," Proper said.
Proper confirmed ongoing dialog with club officials regarding his desire for regular playing time before the transfer market closes.
"I have had conversations with technical director Carlos Aalbers. In those, among other things, I said that I need to make more minutes.
I also discussed that with the manager," Proper said. "There is always a chance that you leave.
But again, I want to convince them. I train well, I play well.
Then it's up to the coach."
