To me that is silly, 
I was broughtg up supporting Motherwell. 
I have an Uncle who supports Celtic. he's a good bloke and I see him often, hell I've even been to glasgow and parkhead. I used to see them on scotsport. 
I have no good feeling toward Celtic. 
  
  
  
  
 
  
I don't even usually bother with the champions league. Love MOTD though
