Sparta Rotterdam starlet Marvin Emnes is attracting a great deal of attention.
Emnes' agent has revealed that the 19-year-old forward has a host of clubs keeping tabs on his progress.
However, Sparta have him under contract for another two years and want him to extend his stay further.
"The interest in Marvin is really gigantic," Eduard Burleson told Voetbal International.
"But the interest dates from much longer, Marvin is now playing as everybody knows he can and expects of him.
"We know that the interest in him is a luxury, but that doesn't make it less complicated - he is on a kind of crossroad. What is best for him?
"That is why we have decided to come together and see what is best for Marvin."
Sparta's technical director Danny Blind is not concerned by the interest in Emnes.
"About that [his contract] we have already spoken and we will probably do it again next week," said Blind.
"Marvin is still under contract for two years."
