Boss Arsene Wenger says Arsenal created enough chances to beat Chelsea on Sunday afternoon.
The Gunners could only manage a draw against the Blues in what was their last chance to keep their title hopes alive.
The 65-year-old was also honest enough to admit that Chelsea should have been given a penalty after goalkeeper David Ospina clashed into midfielder Oscar.
"We were disappointed because we wanted to win but we didn't manage to score," Wenger said.
"I think we did enough to win the game today and Chelsea defended well. I felt that we played with the right intensity in the first half.
"We dropped that in the second half and came back to the right level in the last 20 minutes. We could have finished the game off. [Mesut] Ozil had a good chance in the final minute of the game but they came to defend well, did it well and everybody knows that.
"I think we could have had one or two [penalties] as well [but] yes, [we were fortunate].
"The referee played advantage to Oscar. He was first on the ball so he played advantage but Hector Bellerin managed to save a goal, so it was difficult for him [to pull play back].
"I haven't seen it [Cazorla's shot blocked with a hand] but you can always debate on that. I haven't seen it again."
Asked to comment on the hostile reception the Arsenal fans gave to former captain Cesc Fabregas, the Frenchman said: "I've seen much worse."
