Why is it weird? Both spurs and Arsenal were close to where I lived as a kid. And now I live close to Philadelphia. Seems reasonable to me.
The concept of having a choice between 2 such fierce rivals.
I suppose the whole concept of 'picking' a team (especially one that is a competitor of your current team) is what's weird to me.
Surely there has to be a 'reason'. A preference involved? Not just, i used to live near there.
(The Phili one makes sense. It's the Arsenal/Spurs thing)
I don't support very many foreign teams. But i follow a few due to specific reasons. Lazio (football Italia on C4 and Gazza in a mask), Deportivo (Millennium Champ Man colossi with McKaay & Tristan) and Ajax (because: 90s).
I couldn't just pick a German or Portugese team to follow though.
