Wouldn’t this be the case for any Under-21s manager?

England Under-21 manager Aidy Boothroyd believes it is not possible to succeed in the role, as his side face a second successive group-stage exit from the European Championship.

Defeats against Switzerland and Portugal mean England must beat Croatia to have any chance of reaching this summer's quarter-finals.

"The England senior men's job was called the impossible job," he said.

"The England U21 team is the utterly impossible job."

Boothroyd, who led the under-21s to the last four in 2017, said the way the England international set-up is structured limits the chances of the U21s winning tournaments.

"It's not possible to win at all levels," said Boothroyd.

"Part of the reason we haven't won this for 37 years is [that the under-21s' role is] to get players to the first team."
