Mauricio Pochettino has criticised his forwards for their lack of ruthlessness in front of goal as Tottenham lost 1-0 to Bayer Leverkusen.

The North London giants lacked a cutting edge in front of goal on Wednesday night, as Spurs’ Champions League hopes hang by a thread.

Speaking to Tottenham’s official website, Pochettino revealed that Tottenham’s attacked lacked “energy” and “aggression” as they failed to score for the third time in six matches.

“I’m very disappointed, we were poor and the result wasn’t good,” Pochettino revealed. “We didn’t play well in the (home) games against Monaco and Bayer Leverkusen.

“We showed a lack of energy and a lack of aggression in front of goal and when you play in the Champions League, it’s important to show more quality, more energy.”

South Korea international Son Heung-Min started as Spurs’ centre forward, before Vincent Janssen came on in the first half in place of midfielder Moussa Dembele.

However, the £17million signing failed to break his goalscoring duck from open play as Spurs came closest through Eric Dier who cracked a free kick against Bernd Leno’s crossbar.

Star striker Harry Kane continues to be sidelined for Spurs after injuring his ankle against Sunderland in September, but could return on Sunday during the North London derby.

Spurs’ loss means they now sit in third place in Group E, with just two games to claw back league leaders Monaco who sit four points ahead.
