Pompey to cancel first home game?

Just read in yesterdays Daily Mail that Gaydamak who used to own Pompey is holding the club to ransom as he stills owns the land next to Fratton Park and insists that he has not been paid rent for the use of the car parking.
He did however let them use the car park yesterday for Linvoy Primus testimonial. If Gaydamak sticks to his plan, then Pompey would have to cancel their first home game of the season.

Why would they have to postponne the game if their car park is closed?

What's wrong with walking? Buses?

Games don't stop in London when bus drivers or undeground staff go on strike.
