Southgate's decisions not to gamble * just paid off in the semi but not in the final. Viewed from one angle, England played the "best team in the tournament" who were unable to beat them, but from another, they had a lead over the "best team in the tournament" for most of the game & when it was obvious something needed to change, they didn't make a change. Contrasted with Italy who did make a change which turned the game around. For me, absolutely indefensible tactical failure from Southgate. For once, England had a good squad, not just a handful of individuals and a Plan A but nothing else. The one bonus on seeing his starting XI was to then see the bench options, which premier league manager wouldn't kill for those options to be able to bring on!!
I have to say, I did have that realisation before the game: "It's Mancini vs Southgate!" Easy to get swept along with the optimism, but that was the reality.
And all this is before we get to the penalty shitshow, or how he stuck on Sancho and Rashford just for penalties. Really amateur stuff. Why not stick them on sooner? What have you got to lose? Even after Italy equalised, it was obvious we needed some fresh legs, nevermind that we had a £multi-million bench!
A big missed chance, when other results had really fallen for England.
One interesting thing when it comes to England. This is one time where English fans get to learn a little of what it's like to be a United fan. Everyone is out to belittle your achievement and being "anyone but England".
* Not really much of a gamble really, changing things with 20 mins to go when things are clearly getting away from you and key players are tired, not playing well or just not getting the ball (Rice, Mount, Kane ...)
