I have my doubts the England players will be flying. Southgate is their manager. They'll meet up for the World Cup and he'll feed them with another large dose of negativity. His game plan will be to try and win the world cup by getting a draw and a couple of narrow wins in the group stages, and then winning all the knockout games 1-0. Of course, England may well score an early goal, and for the next 80 or so minutes they'll sit back and play ultra defensive. Invite the opposition on, and England end up losing 2-1 or 3-1. When the opposition score, England will struggle to get back any attacking momentum.
I could be wrong, but it is my best guess at this stage.
