Vincent Janssen has scored just one goal for Tottenham Hotspur so far.
Osvaldo Ardiles has admitted on social media website Twitter that he is worried about Tottenham Hotspur striker Vincent Janssen.
The summer signing from AZ Alkmaar has made a slow start at Spurs, with his performances coming under scrutiny.
Janssen was selected to start for Tottenham in their 1-0 win over CSKA Moscow in the Champions League last night, but he failed to impress.
The Dutch striker found it difficult to get involved in the match, and never really had a chance to score his second goal for the club.
Ardiles was generally impressed with Spurs’ performance in Russia, but he does admit to being concerned about Janssen.
Janssen is yet to score for Tottenham from open play, with his only goal in a competitive match coming from the penalty spot against League One side Gillingham.
The powerful forward is likely to be persisted with, though, as Harry Kane is currently out injured – meaning there is a place for grabs up front.
Tottenham’s next match comes against top of the table Manchester City at the weekend.
