I am chuffed at how well they did, and exceeding most people's expectation. We are far from perfect, but most countries do NOT win things. Perhaps we have underachieved over the years, perhaps not. Regardless, we cannot judge this team on the results of those who went before them.
They did well. They've given us hope for the future, not reasons to think they'll do badly. How we as fans behave is also something not beyond reproach.
There is nothing gracious in a fan who seeks to stick the boot in once we've lost. We can all looks at reasons why we didn't win, but there are ways of expressing that. There is always room for improvement, even in the winning side, Italy.
Given that we came so close - there shouldn't be too much to have to change.
