No, that's changing words. A weaker than usual German side, and an Italian side that was tipped to be exiting early doors, that's not saying they were bad, that's saying these were very clearly understrength compared to years gone by.
I'll put the achievements into context, yes, teams get absolutely lucky and good draws and to win a tournament you generally have 2 or so tough games and those are what win you the tournament. Spain when they won it had what, two hard games? But they matched those tests and got through to win. England faced two stern tests, Croatia and Italy, they lost both. So laud getting there but there will be perspective that it was an easy ride till things got tough and then failed when it mattered.
And no, that makes no sense, id rather England kept Southgate, with a top level manager (say a Mancini), England would have won the Euros.
