In my time as a fan, it's not even close to the worst performance. When I look at the squads we had, the results we had, and performances it's 9th best out of 21 and if we beat switzerland to reach a semi will go higher:
WC 18 - semi
EU 20 - final
WC 90 - semi
EU 96 - 1/4
WC 22 - 1/4
WC 06 - 1/4
WC 82 - 2nd group
WC 86 - 1/4
EU 24 <--- could go upwards
EU 12 - 1/4
EU 04 - 1/4
WC 02 - 1/4
WC 98 - round 16
EU 16 - round 16
WC 10 - round 16 with our best ever squad
EU 92 - group stage
EU 00 - group stage
WC 14 - group stage
EU 88 - group stage
EU 08 - DQN
WC 94 - DNQ
W/C 2010 was our best squad? We had rob green/ david james, glen johnson, aaron lennon, milner and heskey all starting. Would any of those get in this side?
It's hard to just go off semi, final, quarter final etc, depends on quality of oppo, and the route you gotta take to get to the final I think.
Euro 96 was a semi though and not a quarter final, and we lost to the winners, who were a good side. That England side would beat this one, all things being equal. That side beat Netherlands and Spain etc, and should have beat Germany. Will take some doing to top that and getting to a semi won't match it.
Same as Italia 90, semi was a good result in that, being knocked out by the winners, we didn't really win any "hard" games though I suppose.
W/C 2002 we lost to brazil in the quarters, who won it comfortably. They had a mint side and we gave them their hardest game I think.
2018 word cup we had a pretty easy route, and got knocked out in the semi by Croatia who lost comfortably to France. A "semi loss" doesn't mean a great deal here I think.
Euro 20 we had a fairly easy route, in the much easier side of the draw and only won one hard game against the Germans, but even their side wasn't that strong, or isn't as good as it is now. Italy were not great and beat us in the final, and they did that to 3/4 other good sides as well as us.
World Cup 22, we didn't beat a good side, lost to France first hurdle who got to the final and lost.
For me I think a fair judgement is by judging who you play and who you beat, we don't actually seem to win many of the tough games these days, we're more like flat track bullies (sometimes).
