The Dutchman has been struggling for form at White Hart Lane.
Much has been made in the press of Vincent Janssen’s recent display against Aston Villa in the FA Cup. The Dutchman put in a poor display which caused further concern over his long-term suitability to be a back-up to Harry Kane.
One man who was very concerned with the performance was former Dutch international Wim Kieft.
The former Ajax and PSV star was himself a striker, who scored 11 goals in 42 caps for the Netherlands.
Tottenham's Vincent Janssen in action
He wrote his concerns in De Telegraaf this weekend, suggesting that Dutch national team coach Danny Blind will be very concerned with Janssen’s situation at White Hart Lane:
“Even against Aston Villa you could see that Janssen lacked that good feeling.
“Tottenham will win prizes, join to place the title in the Premier League and qualified for the Champions League. Such a club not treat themselves time to purchases.
“Nobody should be surprised if Spurs start looking for a new striker. "
"Meanwhile, head coach Danny Blind must seriously concerned about the lack of progress on Janssen because there occurs no improvement then then for Oranje (Dutch national team)."
Tottenham's Vincent Janssen reacts
Janssen has simply not done the job for Spurs since his move from AZ Alkmaar in the summer. He is still to score from open play and looks to be a yard off the pace necessary to compete in the English top-flight.
He cost the club, according to Sky Sports, around £18.6 million and was supposed to be a natural goal threat as his record of 30 goals in 43 appearances would have suggested last season.
Spurs fans will hope he can start to find a streak soon or the club may need to start thinking of other options.
