Scotland manager Steve Clarke confirmed his continued interest in capping Elliot Anderson and refused to rule out a move for Harvey Barnes after Tuesday's friendly against England.
Anderson spent two days with Scotland last week before withdrawing from the squad and England manager Gareth Southgate has since expressed admiration for the Newcastle midfielder and stated his backroom team would be taking the situation up.
Clarke said: 'We like the player as well so Elliot will still have that choice to make.
'When I come out of this camp I will look at what we have done, what we have had, what's occurred over this camp, we will do a debrief on it and then we will shape what we do from there.
