One of the most fascinating things for me when I watch modern-day football is that it feels like no-one values defending properly any more.
Over the past few years, the Premier League has developed a more possession-based strategy and, individually and collectively, defending has without doubt been restricted by our obsession to play football 'the right way'.
That's why I think what Mikel Arteta has done at Arsenal is brilliant, because although their attacking play is still amazing, he has looked at the stats that really matter and seen that all good teams are built from the back.
The way Tottenham have changed under Thomas Frank this season is based on the same way of thinking, of finding a balance between scoring goals and stopping them, and both coaches understand the importance of a team's structure in and out of possession.
That means Sunday might not see the kind of high-scoring game we have been used to when these two teams have met in recent years - the fixture has averaged more than three goals per game over the past five seasons - but it is a north London derby so anything can happen!
