Which ones?
2004 maybe, but it's essentially the only time they forced Gerrard, Lampard and Scholes together like that and well, it worked... until Rooney's injury, but even then, they should have won that game. Sol's goal was perfectly fine. No Rooney injury, they win that tournament for me and many others, but definitely make the semi's. He likely would have moved towards a 451 in the semi.
2006... dunno, this is more a selection issue, should never have taken both Owen and Rooney, if either, but the consensus was, half-fit of those were better than starting Crouch-Bent/Defoe etc, but obviously he shouldn't be dropping those guys for Walcott who he had zero intention of using. He played a 451 in the knockouts, which everyone wanted, and it barely worked, mostly because the 1 was a half fit Rooney.... again, fit Rooney, and I'm comfortably in thinking they beat Portugal.
I definitely think if Kane had the same injury issues, Southgates record wouldn't be as good either, all while having better fixtures.
