Chelsea are going to ban players from international duty.
Like many other managers, Tuchel is worried about the international break as the Blues squad host a number of international players who could be required to travel overseas to represent their country.
The UK currently has a 10-day quarantine rule which requires any international player to stay in a hotel when he returns to England.
“I am absolutely worried because my target is to play in the Premier League and if I have players in quarantine, I cannot build the group that we want,” Tuchel said after his side’s 1-0 win over Liverpool on Thursday.
“This is the risk and I am absolutely worried about this situation. But I am also sure that the club knows how to handle it. If it maybe is the consequence that the players cannot go then this is the consequence.
“This situation is extraordinary. We have to adapt and we will do this as a club and we will make these decisions. We are very concerned about the situation.”
