Just to make you all aware of the 90 minute limit on matchdays ( including Man U womens wendyball)
I recently received a £100 PCN from Euro Car Parks for being 12m over the time, it took me nearly 25 m to reach the camera at the exit due to the car park staff being unable to organise a p!$$ up in a brewery.
Luckily, I found my two week old till receipt, took it into the store and the manager said he would sort it.
Not everyone may be so lucky, so be aware!

Is Morrisons an official car park for LSV visitors, or is it a run the risk of parking there?

No its not, you risk a fine even shopping there if you cant get off inside 90min, especially just after final whistle.

Was at Morrisons yesterday, there is a sign as soon as you turn into Morrisons saying car park is not for matchday parking. So in fairness, if your using it to go to a game then accept the consequences when caught.

You can park as long as you want if you tow a caravan and tie a dog up outside ..all for free
