Greece has done in 2004 what England never managed because it didn't throw away the lead!
With 20 years distance since the biggest surprise in European football, maybe in world football, of Greece winning the European Championship back in 2004, honestly I can say that the Greek national team did exactly what England should have done in more than one cases in the past... Being more clinical and cynical and not throw away the lead. Sounds simple, right? But at the same time is the most difficult thing in football!
