Tottenham head coach Andre Villas-Boas’ career may be in doubt if the Portuguese fails to lead them to the Champions League this season, with former player Jurgen Klinsmann reportedly on the shortlist to replace him.

Qualifying for the Champions League is thought to be an absolute must for Villas-Boas after being handed a large transfer budget over the summer.

Due to Spurs lack of goals so far this season, Villas-Boas may be backed again in January but there will be no more room for error.

If Spurs fail again to reach the top four, former German player and manager Jurgen Klinsmann could be approached after the 2014 World Cup.

The White Hart Lane fans' favourite was linked with the vacant Spurs post last summer after Harry Redknapp was sacked but Klinsmann distanced himself from the role.

"It just isn’t a realistic proposition for Jurgen at the moment," a spokesperson said.

"The timing isn’t right. He has no thoughts of leaving the post he has at the moment and is totally committed to leading the United States into the next World Cup."
