Watt's heading in the right direction for another call up, but if there's one thing you can count on with Steve Clarke it's that he likes to stick with what he has. And given the result from the Austria game, he was never going to deviate far from that set of players.
While that's tougher on guys like Watt trying to get into the squad, it's better for guys like O'Donnell who Clarke trusts to execute his game plan (regardless of what some people on here think of him).
