I just took it from a tweet I saw earlier which stated 15/21 qualifiers we have won vs 2 in 19 friendlies. I know which ones I'd rather win.
Here's a stat for you: last 2 euros= 2 qualifications, is that too selective for you? Tartan Army are the most negative people in the world. Cry for years we don;t qualify or bad luck blah blah, actually qualify 2 times and some want the manager sacked. It's ludicrous.
