Martin Keown believes that Tottenham aren’t strong enough in the central forward area without star man Harry Kane.

The England international suffered an ankle injury during a Premier League clash against Sunderland and is expecting a lengthy period on the sidelines.

New signing Vincent Janssen alongside South Korea international Son Heung-min have both stepped in for Kane, but Keown doesn’t believe that either are good enough.

“Without Kane, are they strong enough in that central area,” Keown said to the Mail. “Tottenham will attack you from all angles but they look a little short in that central position.

“Son has started well but Vincent Janssen doesn’t quite look ready for the Premier League.”

Kane started the season in bad form in front of goal, which had continued from the summer’s European Championships.

The 23-year-old had scored just two goals in seven appearances for his club, which to his high goal scoring standards was well below par.

Janssen is still adapting to the Premier League following his £17million summer signing from Dutch side AZ Alkmaar and he has scored just one goal in 10 appearances in all competitions in the new campaign.

Meanwhile, Son, who almost left the club during the summer seems to have been given a new lease of life.

The attacker has scored five goals in six appearances in all competitions this season and was chosen to lead the line for the first time this campaign during Sunday’s 2-0 victory against Manchester City.

Spurs are currently sat in second place in the league and one point behind league leaders Manchester City as they look to improve on last season’s third place finish.
