Spurs drew 1-1 with Besiktas in the Europa League last night, meaning they have now only won one of their last seven games, and the result will have frustrated many Spurs fans as it looked as though they had the game wrapped up.
A late defensive tragedy for Vlad Chiriches saw him miss the ball with the clearance, before sticking his hand out to concede a penalty in the dying minutes.
The Romanian centre-back looked vulnerable for the entire game, and failed to deal with the majority of attacks that came his way.
He ended up conceding three fouls during the match and was totally outperformed by Spurs' other centre-back Federico Fazio - who looks to be closing in on some first-team action in the Premier League.
Besiktas deserved something from the game, but with Spurs looking relatively comfortable late on, Chiriches' appalling defensive duties cost his team two vital points.
He has yet to establish himself as a first-team regular since joining Spurs last summer, and time is surely running out for the erratic 24-year-old.
Another player who has failed to show any promise so far this season in Paulinho, and the Brazilian had another evening to forget last night.
He made a relatively solid start to life with Spurs last season, but has since been largely ineffective and fails to influence the game defensively, or offensively.
Only Roberto Soldado completed less passes (22) than Paulinho (23) last night, and the 26-year-old is another whose time at White Hart Lane could be coming to an end sooner rather than later.
Tottenham paid out £17 million to land the former Corinthians star, but his inconsistency, and failure to influence games for Spurs make it difficult to justify just why the club paid out so much.
He has not recovered from a poor World Cup display, and with Benjamin Stambouli, Nabil Bentaleb, Moussa Dembele, Etienne Capoue and now Ryan Mason also fighting for starts in the centre of midfield, Paulinho's time in north London could be over come the end of January.
Mauricio Pochettino welcomes his former side Southampton to White Hart Lane on Sunday, with Spurs desperate for an overdue win in the Premier League, and it is unlikely that either Chiriches or Paulinho will feature.
Is time running out for Chiriches and Paulinho?
