The FA is investigating media reports in Iceland that Greenwood and Foden broke quarantine rules while at their team hotel in Reykjavik.

Iceland's police force has said the players have each been fined 250,000 Icelandic Krona (£1,360) for the rule breach, which must be paid by the individuals themselves and not by the FA or their clubs.

Southgate confirmed the pair broke coronavirus secure bubble guidelines and have been sent back to England, without contact with any other players since Monday morning.

"Unfortunately this morning it was brought to my attention that the two boys have broken the Covid guidelines in terms of our secure bubble.

"We had to decide very quickly that they could not have any interaction with the team, wouldn't be able to train. Given the procedures we have to follow now, they have to travel back to England separately."

Southgate said the breach had occurred outside of the part of the hotel the FA has booked for the England squad.

"Nothing has happened in the areas we occupy in the team hotel," he insisted.

"We are still getting to the depths of all the information because it was only brought to my attention only a couple of hours before training, I am still getting to grips with some of the detail.

In the meantime both players have "apologised for their serious lack of judgement";
