Pundit Shaka Hislop has insisted that he is not yet convinced by new Tottenham striker signing Vincent Janssen.

Janssen, 22, has struggled since his summer arrival and is yet to prove a consistent threat to top flight defences.

The Dutch striker has made 10 appearances for Spurs this season and his only goal was a penalty against Gillingham in the EFL Cup.

Asked by sports broadcaster ESPN whether Janssen is hit or miss since his arrival, Hislop said: “He goes in the miss column as well. Janssen came in with a lot of accolades, and he was given an opportunity due to the injury of Harry Kane, but everytime I see him I’ve not been all that convinced. He goes down as a miss, so far.”

The forward was signed for £18million from Dutch side AZ Alkmaar to provide competition for first-choice Spurs spearhead Harry Kane.

An ankle injury to Kane paved the way for Janssen to have a regular run in the team but he had only mixed success in three consecutive starts and manager Mauricio Pochettino selected Heung-Min Son as the spearhead in last Sunday’s 2-0 win over Manchester City.

Janssen, who netted 32 times in just 49 appearances for his former club AZ last season, remains a regular starter for Holland.

He scored a stunning goal as they beat Belarus 4-1 in a World Cup qualifier on Friday night.
