As baffling as Trippier's inclusion is, besides potential set-piece threat, England have got a lot going for them, from back to front.
Midfield was their downfall in 2018, but none of Rice, Philips or Mount were involved then and it looks as though Henderson has been well and truly eclipsed by Bellingham as well, so they've improved where they needed to.
Sterling is frustrating, but was there for his runs in behind the Croatian defence, who were always going to be deep and compact. To be fair to Southgate, it's precisely that that won England the game. For all his faults, his movement must be a nightmare to deal with.
I doubt this will happen, but hopefully the shackles can come off now that qualification is guaranteed and Scotland take a vicious hiding.
