When you look at Roberto de Zerbi, his first stint at Brighton was something that was very transformative to the Premier League.
Many of the coaches adopted his baiting-style of build-up and his idea to punch the passes through the middle of the pitch really quickly.
What we have seen in pre-season is an adaptation and a focus on building upon what he did at the end of last season, which is a more simplistic view.
But he did not come in and simply try to shut up shop and get easy points, he looked to build out from the back and use that short build-up. That tactic is still very key to his side.
What I have noticed is his awareness that teams are pressing man-for-man in a really aggressive manner. There has been a focus on building through the middle, but also on building out under pressure using the same ideas in wide areas.
Those moves tend to finish with the wingers one-v-one, so De Zerbi is not just using his principles through the middle but also through the wide areas to still arrive in the final third really quickly and really aggressively.
A lot of the top coaches have one set style of play in mind - and De Zerbi has certain principles - but a few years ago he said: "When you're building the play, if the rival doesn't pressure us intensely then we slowly move the ball up the pitch. When they do pressure us, then we can make some passes, dribble and play more vertically."
He is a coach who adapts how his team builds up and plays depending on how the opponent defends, which is slightly more reactive and adaptable.
The biggest challenge is teams will increasingly sit back and almost ask his players to break them down, knowing what De Zerbi prefers to do, so it is all about how he then looks to break down stubborn defences that sit lower.
