That goal changed the match, let me tell you why.
When that goal was disallowed it meant that England had to put more players up in attack every time they went forward, that's why you had John terry up in the box during quite a few of their attacking runs. This extra attention to the offence meant that Germany was able to effectively play the counter attack against us, a tactic that wouldn't have worked quite as well if England were playing under an equal score line.
That being said, there was some absolutely piss poor defending going on at our end, Gareth Barry showed all the pace of stephen hawking travelling uphill and some of the defensive errors were things that you would expect from 12 year olds.
Milner is another player so lacking in pace that he might as well be carrying a ball and chain and between him and Aaron Lennon there's not much to choose since they're both playing like sh*t. At least Lennon is fast, though.
Lampard obviously really came through in this match and he can feel extremely unlucky not to have at least one goal. As for the Germans they definitely benefited from the lackluster English defence but they're obviously still as weak in the air as they were in 1940 since we dominated headers and were able to play the long ball game pretty damn effectively.
Obviously the thing we can take away from this is that the FA needs to do a bit of soul (and player) searching and FIFA needs to take their heads out of Pele's ass and allow goal line technology.
Interesting side note: the referee in this game did the exact same thing (vis a vis goal) in 2006 and in 2002 he was suspended on charges of corruption from fellow referees.
