For a few years now the North London derby has been establishing a significance beyond local rivalry. Tottenham Hotspur's re-emergence as a club capable of competing near the top of the table has drawn them into Arsenal's sphere of competition.
Their late-season clashes in particular have had increasing ramifications, though their meeting just over a year ago was the first since 2006 when the result had such a direct impact on both teams.
The same is almost certain to be true of Sunday's fixture at White Hart Lane. Tottenham sit in third place, four points ahead of Arsenal, and will be keen to avoid a result that instigates a collapse similar to what they suffered last season. Arsene Wenger, meanwhile, will be desperate for his team to get a win that sets them on the path to consolidating another top-four place.
North London derbies rarely disappoint for entertainment, and with so much on the line this has the potential to be memorable one.
Here are a few key battles to keep an eye on.
