Even after the night, there was still a portion of England supporters who could not believe this fact—They actually defeated Portugal by a 4:2 scoreline.
That match was like a dream and it left a deep impression on them.
No matter what, Portugal was still a traditionally strong team in Europe and logically speaking, they were equal to the England team. That's why, while it was not a big shock that England defeated Portugal, to win so easily with a score of 4:2 was unusual.
Even though England did not play much better than Portugal throughout the whole match, the scoreline said it all. 4:2 was a score that could really enable them to hold their heads up high.
