Arsenal let a two-goal lead evaporate against Spurs at White Hart Lane and, in many observers' eyes, killed off their hopes of overtaking Manchester United for the Premier League crown.
With champions Chelsea winning 3-1 at home against Birmingham City, Arsenal slipped from second to third behind Carlo Ancelotti's side on goal difference and seem set for a sixth season without a trophy.
Spurs manager Harry Redknapp was among those who thought Arsenal's failure to win had severely damaged their chances of lifting the title for the first time since 2004.
"They have gone 16 games unbeaten in the League and you don't do that without any bottle," Redknapp said afterwards.
"But it is going to be hard for them to catch Manchester United now, although you never know. Chelsea might win every game and its not the first time we have seen big leads turn around, but it was a bad result for Arsenal tonight and a very good result for Manchester United."
"It is not over, we will fight until the end," he told reporters. "Chelsea are back in the race and it is down to us to keep our faith and keep battling and we will not always draw when we score three goals."
Arsenal's next match is on Sunday at Bolton, who will be keen to make up for their 5-0 drubbing by Stoke City in the FA Cup semi-final last Sunday.
Chelsea have emerged as United's closest challengers, showing many of the qualities that made them champions by demolishing Birmingham on Wednesday.
"Obviously I would like to be in United's position, six points ahead," he said.
"That's a lot at this stage of the season, but in football anything can happen right up until the final whistle. You can win the title in the last minute and you can lose the title in the last minute."
While Wednesday's match at White Hart Lane dented Arsenal's title hopes, it also did little for Spurs' chances of finishing in the top four and qualifying for the Champions League.
