New UK government guidance means Premier League players and coaches will be required to isolate for 10 days following any overseas trip, complicating the schedules of teams still in the Champions League and Europa League.
Prior to Sunday's new restrictions being detailed to all 20 Premier League clubs, revealed by the Athletic, there were no targeted guidelines for players and staff returning from overseas trips.
The 10-day period can be reduced by half if a player of staff member can provide a negative Covid-19 test following a five-day isolation.
