From the OS:

Bags bigger than A4 are not allowed in the Etihad Stadium. If you do have a bag bigger than A4, consider storing it at an off-site location by

If you must bring a bag to the stadium that exceeds the allowable size, the bag storage facilities are available on the Orange car park that you can use to securely store your items will be in place until the match has finished. The bag storage is priced at £10 per item.
So why the fuck can away fans bring in huge drums that suck the life out of any atmosphere from the home fans. Home teams used to and probably still do try ever6 trick in the hook to unsettle away teams. Fuck me certain clubs still have an exemption to not offer pitch side seats or have large screens. But not City, we allow away fans to make themselves at home to the detriment of the club. Pretty much made my mind up to sack off CL next season. Bloody expensive, midweek late kick offs, surrounded by away fans, drum going thud all match and Pep taking the piss with his team selection.
