Arsenal were left to reflect on what might have been following Saturday's dramatic draw with Norwich City.
In a game that ebbed and flowed throughout Arsenal struck early courtesy of a delightful Yossi Benayoun goal.
But Norwich responded with two of their own before the interval from Wes Hoolahan and Grant Holt.
Following the introduction of Alex Oxlade Chamberlain Arsenal improved, with a brace from the excellent Robin Van Persie.
Five minutes from time, though, Norwich levelled again when substitute Steve Morison netted from an acute angle.
In the closing stages Norwich custodian John Ruddy saved from Van Persie, while Arsenal might have been awarded a penalty when the Footballer of the Year appeared to be fouled by Kyle Naughton.
Arsene Wenger was disappointed with the decision. "I don't know, we have to accept the decisions of the referee, that is the only thing I can say. Here, the whole season we have got zero penalties. It is absolutely amazing because you see other clubs who have 10 or 11.
"It is more than frustrating because we were very poor in the first half, not switched on. The quality of our first half was absolutely not at the level we wanted in a decisive game like that. in the second half we did very well.
"We created at least 10 chances but again not only did we not take our chances, but on top of that we gave them a third goal in a situation that was absolutely unbelievable. In the end we got punished for our mistakes."
Having contributed so much to a thrilling encounter Norwich boss Paul Lambert was thrilled with the Canaries character throughout. "I've said to the players that I'm so proud of what they've given this season and this highlighted it even more. We were outstanding. I thought Spurs was as good as anything in my time here but this might surpass it."
It was a bad day for the Gunners with right back Bacary Sagna suffering another severe foot injury which will rule him out of the France squad for the upcoming European Championships.
Benayoun hopes Sagna makes a swift recovery. "I don't know exactly what happened, but it looked like a bad one and he had a big one already this season.
"It was similar in the same area as the last one but I hope he will recover quickly because he's a great player and that's more important than any points or win and hope he can recover quickly."
