I supported England in World Cup 90 in Italy. Since then I haven`t found much pleasure in watching England (with a few exceptions). If we think about the size of your country, your football league, your general physics as average western europeans with also lots of muscular afro-british citizens, your sports fascilities etc., there`s no logical reason why England have a poor team compared to Germany, Italy, France, Holland, Belgium or Spain.
Especially compared to Holland and Belgium it`s a mystery why you don`t achieve more on the pitch with that players and team.
