Technical director Carlos Bocanegra was asked if Mercedes-Benz Stadium will rival the world’s soccer cathedrals, like Old Trafford, Anfield and Camp Nou. Bocanegra said owner Arthur Blank, the architects, engineers and construction companies have done everything to make the stadium Atlanta United’s, from the parking, the entries, the retractable seats, the drop-down curtains. “It will be the best stadium in the world until something else is built,” he said. Bocanegra was able to test the synthetic turf playing surface that will be installed. He said he has played on turn at Portland and Seattle, but this will be better. He said the fibers are sewn in different directions, which provides multi-directional give, which feels more natural and provides truer rolls.
