With Gunn and McCrorie likely to be out of Monday's friendly against Liechtenstein, too, and Slicker's confidence through the floor, will Clarke turn to someone else? "You have to find out what's in the player's mind as well, how he's feeling about it," former Scotland defender Willie Miller said of Slicker. The two-time Scotland cap, 37, only played one FA Cup game for Swansea City last season and is now out of contract. But he was a squad regular, is experienced, and would likely be considered one of the safest options. Other Scotland-based options would be Scott Bain - recently released by Celtic - or Ross Doohan - recently signed by Celtic.
