Chelsea and Manchester City fans should not travel to Turkey for the Champions League final, says transport secretary Grant Shapps, after he added the country to England's travel red list.
Schapps said Covid-19 red list countries "should not be visited except in the most extreme circumstances".
He added that the government was open to hosting the game in the UK.
Uefa had hoped to give both clubs a minimum of 4,000 tickets each for the game at the Ataturk Olympic Stadium.
Schapps said that the Football Association is in talks with Uefa about switching the game, but that it is "ultimately a decision for Uefa".
