One big problem is that the trains finish too early at night matches to use a lot of park and ride facilities. For example the last train to Horwich Parkway goes before the match ends. Northern Rail is beyond a joke. It's easy to get around the central core of Manchester using public transport but not easy to get in from outer areas. It's amazing how easy it is to get in and out of Wembley via Wembley Stadium Station, much easier than the Etihad.
