A disappointed Tottenham manager Mauricio Pochettino has accused his players of not respecting the plan after they threw away a two-goal lead to draw 2-2 at Olympiakos in their Champions League opener on Wednesday.
Tottenham had gone ahead through Harry Kane's penalty and Lucas Moura's superb strike, but Olympiakos hit back before half-time through Daniel Podence.
Pochettino's men then conceded a penalty which Mathieu Valbuena converted in the 54th minute.
"I feel very disappointed. To be honest, first half I wasn't happy with our performance," Pochettino said.
"From the beginning we had a plan. We didn't respect the plan. I told the players at half-time. We scored two goals but if you only analyse the performance it wasn't great.
"We conceded a lot of chances to them and the first goal was painful. We didn't show the aggression these games demand."
Tottenham will play Bayern Munich in their next Group B match.
