Definitely mostly 1. Any match during school holidays, even half terms, usually has lots of tickets available. Lots of families don't plan their lives around football.
Probably equivalent to 2 weeks wages for Sanchez who is currently refusing to sit on the bench. It isn't much in the grand scheme of things. The longer we stay in the PL the more the demand for away tickets will grow so less likely we won't be selling the full allocation.
