Tottenham started their Champions League campaign with a draw against Olympiakos on Wednesday night.
Spurs threw away a two-goal lead and were forced to settle for a point in their Champions League Group B opener in Greece on Wednesday night.
While Spurs fans were disappointed with the performances of Christian Eriksen and Ben Davies, football pundit Matt Upson felt Tanguy Ndombele was below par as well.
The 22-year-old, who joined Spurs on a record transfer fee this summer, made his first Champions League appearance for his new club.
Ndombele was brilliant was Lyon for last season in European games and expectations are high from the midfielder, who is on £200k-per-week wages at the club.
