As a kid I supported Sampdoria because I had the top and, rightly or wrongly, I figured they were quite a close 'fit' with us. But Italian obviously.
Also went to Berwick as a nipper and saw them play in a pre-season friendly against Middlesboro. Was only about 8 and I wrote them a letter afterwards asking about general info on the club and how much their scarves were etc. This was pre-internet.
Their club secretary wrote back a really nice reply - plainly chuffed that someone had taken the time to write him this letter - and so I've rooted for them ever since.
