Not when title is involved, was it not the same Tottenham that Arsenal scored 3 goals in the first half? Manchester City won't allow Tottenham spoil their party, moreover Tottenham and Arsenal are eternal rivals, and when it comes to Tottenham to aiding Arsenal to win the league by stopping City I don't see it happening. Tottenham Hotspur will start losing from first half so that Arsenal will will start crying from the beginning. If Tottenham fans could support Bayern Munich to win Arsenal in the Champions league, do you think they will support them to win the premier league? If they Tottenham game is what's left for city to win the league, then it's a walk over for city.
Tottenham is the only hope for Arsenal to stop Manchester City. Ironically, Tottenham fans don't won't that to happen due to their North Londoners rivalry. I think it's reasonable for Arsenal to put hope on Tottenham stopping Manchester City, because Tottenham have a good record of playing against Manchester City. In last five games, the two teams won two games each, this could be the best recent record for any opponents of Manchester City.
I think the sense of rivalry only belong to the fans, Tottenham players and manager won't let their lose easily, because their reputation as professionals is on the line. They also have aspiration to finish top four that means they need to win the match for themself. If they lose the match, their chance to play in Champions League next season can be over, if Aston Villa win their game.
