How has his free speech been infringed upon? Facebook is a private entity and is able to set its own rules of conduct. You could call your boss a ****, but the odds are you're getting the sack - free speech does not equal freedom from consequences.
You'll likely get the 2,200 from the upper tier. Watford and Leicester had the bottom tier a couple of year ago, and I don't think the Met will allow that again given the (understandable) pitch invasion after the Leicester game. Sad, I'd love to see the away end properly full.
