It's always narked me off when someone is in my seat usually because the bloke who's seat I end up in is a lot more forceful about it being his seat than I am.
As the 16/17 season went on more and more away games were selling out. Most grounds had the usual 'block' entrance and you had to enter the correct block (please remember Hillsborough) but seating was where you wanted. Yet to see what the PL dictate to grounds regarding away fans, guess we'll discover Saturday.
