Ross Doohan and Callan McKenna have been called up for the first time

Scotland have called up free agent Ross Doohan and Bournemouth's 18-year-old Callan McKenna for Monday's friendly in Liechtenstein in an attempt to address their goalkeeping crisis.

Angus Gunn and Robby McCrorie have left the squad following Friday's defeat by Iceland.

Cieran Slicker suffered a torrid debut at Hampden after replacing the injured Gunn, McCrorie having picked up a strain in the warm-up.

Scotland head coach Steve Clarke - who had previously warned that his lack of options in the position was a concern - admitted after the game he would be looking for "another goalkeeper in Scotland who's not on holiday".
