The Dutch left-back has been in great form for the club this season.
Willem II have found themselves a gem this season, after snapping up Mitchell Dijks from Ajax in the summer.
The 22-year-old has gone on to impress in Tilburg, so much so he has suitors for his services.
One of the teams said to be keen is Celtic.
The Scotsman linked Celtic with a £900k move for the Dutch left-back at the start of the month. Dijks, who can also play at centre-back, has played 27 times in Eredivisie this season and has impressed for the club, so there is little wonder Celtic are so keen.
However. His manager at Willem II Jurgen Streppel believes that Scotland should not be his next destination. Instead, he thinks Germany is the place for him. He is quoted by Dutch source Omroep Brabant as stating:
"Everyone knows our numbers, so they can just call. But he also has his price.
"He's been a thrill. Big, very strong and quick. He can defend and attack. There are not many good [Dutch] left backs. After Jetro Willems comes Mitchell Dijk, I think. Such good players are hard to detect.
"In the top division in Netherlands he did not look out of place. Maybe even more over time. A few weeks ago I was at Mönchengladbach against Sevilla. This type of full-back in Germany is really written on his body. But he has to play. That he can do here . So he should stay here."
Dijks would be an excellent signing for Celtic, and an approach has been confirmed for the player. Dijks himself told Voetbal that Celtic has made an approach for his services for next season.
At that price he would be an excellent signing, and considering the success Celtic had with Virgil van Dijk, they are not afraid to delve into the Dutch market again.
It remains to be seen whether he heads to Scotland, Germany or stays in Holland.
