Access to the centre will be barricaded off and the small entry to the shops will be manned by staff enforcing the no entry plan.
A West Ham source told ClaretandHugh: ” Barriers are being put in place now because its harder to do when the shops are open and the area is full of people.
“Stewards and signage will direct fans to take this route via Montfitchet Way. Up to an hour before kick-off people are free to go anyway but from one hour before kick-off everyone will be directed that way.”
She added: “The Stadium looks incredible by the way – I think fans are going to love it!”
