The Dutch striker has had an excellent season with AZ Alkmaar.
Tottenham Hotspur boss Mauricio Pochettino has been spotted attending an international fixture this week.
The Spurs manager was at the game between the Republic of Ireland and Holland last night.

It immediately led to speculation on Twitter that he was keeping tabs on Southampton striker Shane Long. The Irishman had a great season with The Saints and has been mentioned as a potential Spurs target before. He even scored v the Dutch – to catch the eye of the Argentinian.
But perhaps it was the striker for Holland that Poch was, or indeed should, have been looking at.

Vincent Janssen has been in fantastic form for AZ Alkmaar this season.
The Eredivisie striker has scored 27 goals in the league in the 2015-16 season and scored on his international debut for Holland against England recently.
Now it has been reported by Sky Sports that it was indeed Janssen who was the target for Pochettino last night.
Whilst the report claimed Poch was sitting with Long's agent, it claims they already know each other well, and it was in fact Janssen who they were keeping tabs on.
Long would undoubtedly cost Premier League prices and, in all fairness, he is not worth the money being mentioned in the press.

Janssen would come at a cheaper price, is a younger option and carries more of a goal threat than the industrious Long.
This might be the reason why Janssen was the object of Pochettino's attention.
