The Premier League faces opposition over plans to admit away fans for the last two matches of the season.
Clubs fear social distancing may make the prospect impossible, and believe more time is needed to prepare for away fans' return
They also feel that encouraging supporters to travel outside of their local area to attend games would not send the right message during the pandemic.
Sources have revealed that the clubs' views were aired to the league in 'strong terms' on a call featuring various safety officers late last week.
At the last shareholders meeting, competition chiefs outlined their plans — including shifting the calendar to allow for two matches in front of home and away fans.
