I don't belong to Twitter, so the above link "times out" very quickly, but I did notice ther were mentions of the road signs having been changed from Ricoh, and that those within the City, the responsibility of the City Council, had all been changed, but those signs that were the responsibility of Warwickshire CC hadn't been.
On Saturday we went from the match to visit relatives in Fillongley, and heading back,to the M40 vis the city ring road there are still sign that indicate the way to the Ricoh. So assume those are not the responsibility of the City council.
