Wolves captain Conor Coady says the players are desperate for fans to return to stadiums.
The England international feels the removal of crowd scrutiny has seen defending falter and it is 'better for everybody' when fans are allowed back.
"Honestly, they are mad, the scorelines," Coady, speaking ahead of England's friendly with Wales on Thursday, said.
"They're mad. It's a tough one to put your finger on, it really is. You look at it at the start of the season, some teams are ahead of others in terms of fitness, in terms of having a pre-season, and a little bit of extra training.
"The teams that have been in European competition obviously haven't had that, to start off with, to gain that match sharpness at the start of the season, so that might play a bit of a factor.
"I think fans play a big factor, I'll be totally honest with you, I think we all want them back as soon as possible, we've seen other countries doing it now, and it's something we want as soon as possible."
