Roberto Martinez felt leaving Tottenham with nothing was a harsh outcome for his side.
The Blues were more than equal to Spurs throughout the majority of the game and, particularly early on, carved out a number of chances.
But in the end they succumbed to Emmanuel Adebayor’s 65th minute strike - the result of a defensive lapse which the manager was unhappy about.
The Blues boss said: “In football you want to be perfect. We switched off on a free kick half-way inside our half and that should never end up in the back of the net.
“We worked extremely hard defensively and if you had asked me before if I would be happy to restrict Spurs to one shot on target, the answer would be ‘yes’.
“I thought we performed well in the first half and it looked like two teams fighting for different aims.
“(But) if you don’t take chances you are going to make it difficult for yourselves.”
Martinez was also of the belief that a late challenge on Seamus Coleman could well have warranted the awarding of a penalty.
“It looks very clumsy,” he said. “I haven’t seen the replay but Seamus has the ball, there’s no contact with the ball (by the player).
“I don’t know if there was enough contact. It could well have been a penalty on another day.
“But we didn’t seem to get any luck in today’s game.”
