Gareth Southgate has not ruled Mason Mount and Ben Chilwell out of England’s Euro 2020 clash with the Czech Republic, despite the pair being forced to self-isolate after being in contact with Scotland’s Billy Gilmour, who has tested positive for Covid-19.Southgate admitted the uncertainty over the pair was “disruptive” ahead of the game, in which England still need at least a draw to confirm qualification for the last 16 after the goalless draw against their oldest rivals.
