Upsets! No one is safe! As we try to digest Germany’s “negligent”, “haphazard” opening performance and Brazil’s controversial draw, both off the back of Argentina’s dropped points earlier in the week, thoughts naturally shift to the intriguing question: who’s next in line?

And so, with impeccable timing, England open their World Cup campaign later today. Can Tunisia join Mexico, Switzerland and Iceland in getting one over more illustrious opponents?

Yet, surely to suggest such an upset is even possible is to assume England are up there with the likes of Germany, Brazil and Argentina. And rankings, tournament history, national psyche and common sense tell us they are not, although try telling that to cheeky Tunisia coach Nabil Maâloul, who has asserted that Gareth Southgate’s men can go all the way in Russia.

Clearly a born entertainer, that man – much like the majority of Belgium’s squad, who also debut today, against Panama in Sochi, and also with the threat of an upset of their own hanging over them. Hazard, Lukaku and an exciting glut of Belgian talent have been much vaunted for years now but, as England (and Belgium, for that matter) know only too well, converting expectation into actual, real success can sometimes (often) prove difficult (impossible).

A Zlatan-less Sweden complete the day’s agenda (actually they kick it off) against South Korea. More on that one to come as I attempt build the excitement for the next three hours. Simon Burnton will then take over and guide us through until the first kick-off the day, at which time we’ll have separate liveblogs as follows:

3pm MSK/1pm BST/10pm ASET: Sweden South Korea

6pm MSK/4pm BST/1am Tuesday AEST: Belgium v Panama

9pm MSK/7pm BST/4am Tuesday AEST: Tunisia v England
