(Matip strangely came out as Mario in my last post lol)
Although I agree with the obvious concerns with playing Henderson and Rice together, especially the latter, it could well have been a horses for courses line up that didnt quite come off. Kosovo were never a team to sit in but would press high up, the intention may have been to be solid and move it on to more skilled front men.
Southgate has shown as a manager he can be flexible with formations and react, he seems to always be prepared to try things and blood young promising players.
He can't magic up an English Pirlo or KdB, he can't go in the transfer market and buy one either, so he has to find a style that maximises our obvious strong suit, the massive attacking potential while cutting out careless stupid and reckless defending.
Liverpool can compete with City at times despite not having their midfield because they have a system to utilise their front three effectively - maximising their threat on the break. They may lose the media driven all important possession stats and still win games comfortably - proving it's how you utilise your strengths effectively that matters.
England came out top in their Nations League table against Spain and Croatia by playing to their strengths, beating the likes of Spain on their own patch showed we have strengths.
The unfortunate timing of the semi straight after so many of the English team had played in the Champions league final not long before and were deemed unavailable, was disappointing and seriously hampered our efforts, although but for a late VAR decision they might have won anyway despite this.
