Hang on a minute pal.
First off the Watford match on Wednesday is in Bristol - Saturday's game is a long way away and its status will be decided on Friday.
I believe there will be no games within the Met Police boundary in the next day or two, if Watford were playing tonight (Tuesday) I doubt if it would happen.

The rioting hasn't spread to our corner of London, correct? Harrow is fine I think......you can imagine how Watford high street might attract some looters but I'm assuming there's not been trouble.
Your right Ak unfortunately you will always get the brain dead!
