Looking back at all tournaments in my lifetime 1982 and 2004 were the ones where we played consistently well. 2020 (2021) comes into it too but apart from Ukraine the other games were quite edgy.
1980 - Poor and my memory of it was more of the crowd problems.
1982 - Pissed the 1st group and competed well in the 2nd group - should have beaten Spain to go through.
1986 - Crap in the group bar the Poland game, easy next fixture and performed well for last 20 odd minutes against Argentina.
1988 - Appalling
1990 - Crap against the Irish and Egypt but played well against the Dutch in the group. Tough game against Belgium, Cameroon should have beaten us, played well against Germany.
1992 - Crap
1996 - As mentioned above
1998 - Two good group games but poor against Romania - Tough game against Argentina
2000 - Crap
2002 - Group stages were very edgy, good against Denmark, no complaints that Brazil beat us.
2004 - Should have won it. Should have beaten France let alone lose it, easy in the other two games and we'd have beaten Portugal if Rooney had stayed on or if Shearer hadn't retired.
2006 - Edgy in the group, 10 men against Portugal killed us although we did play well with the 10. Hargreaves outstanding in that game.
2010 - Poor and the Germans played us off the park in the 2nd round.
2012 - Ok (ish) but lacking the quality that we have now.
2014 - Crap
2016 - Poor in the group and lost to Iceland.
2018 - Poor in the first game, hammered a mediocre opponent in the 2nd, rested in the 3rd, should have comfortably beaten Colombia, relatively comfortable against the Swedes, Crotia should have been buried by half time. Tactically crap from then on.
2020 - Italy could have been buried by half time. Tactically crap from then on
