The Scotsman says builders left tartan scarves and Scotland shirts under goal lines, penalty spots, the centre circle and the England dugout.
Workers apparently carried out the stunt after being the targets of banter and jokes from English colleagues, about Scotland's failure to make it to the last two World Cups.
Celtic and Scotland legend Billy McNeill said the prank would mean the 1977 rampage would not be repeated.
He said: "At least it will save us taking pieces of turf back home with us again."
Scottish fans notoriously ripping up much of the turf and smashing up the goalposts at the old Wembley after a 2-1 victory in 1977.
