Wolves boss Nuno Espirito Santo has called on the government to accelerate coronavirus testing results as he feels it is hampering clubs' preparation for matches, reports BBC Sport.
The Wolves squad were tested on Friday but will not know their results until Saturday, just 24 hours before they kick-off at London Stadium.
"It's tough for us, you get tested – we got tested today – and we don't know the results," he said. "We're preparing for the match on Sunday and having the stress about the final result, can you use a player, can you not?
"We are living in a bubble and every time a fan asks for a photo or for you to sign something you have to keep your distance. It's very disruptive for preparation and planning.
"Faster results of the test would help all the teams immensely so we can proceed without having these problems."
