I'm going off a local to Old Trafford and what he says they use for concerts.The covers used in co certs (assuming your talking about something like ArmourDeck) takes a crew of 25 approx 6 hours to cover a football pitch, needs underlays of fabric to protect the grass rolled out first, and the takes that same 25 man crew about 7 hours to pick up again.
So I'd respectfully suggest the concert style coverings are not the way.
I've also seen what they use at Durham and is more akin to the covers on the square.
I'm fully aware of what they use at football stadia to protect the pitch.
