Premiership Football

I don't know when you will be in UK but it looks like one off tickets can be bought via a travel company see link for Premier League packages

I am sure this involves a considerable mark up but the company are well known and I am certain the tickets would exist. They also seem to sell Champions League tickets which being played at night matches under floodlights can be more exciting.
City's following is not so widespread as the other team in Manchester whose fans often seem to come from anywhere but Manchester. It is also fun to watch a team away but getting tickets in the away section is more difficult as fewer will be available.

If Man U's play doesn't improve soon they will be giving tickets away;)

You might be able to secure last minute tickets at this resale sight: http://www.viagogo.co.uk/mcfc/Sports-Tickets/Football/Barclays-Premier-League/Manchester-City-Tickets

They have an official arrangement with the team.
