Manager Alex Smith was impressed by Charlie Miller's full international debut in Poland on Wednesday night and promised more to come from the Tannadice midfielder.
"Scotland's next game is not until September and by that time you will see a fitter Charlie Miller because he will have had the benefit of a pre-season with us," said Alex on Thursday. "Having said that, I thought Charlie played well and showed what we have all known for a long time, namely he has the quality to do well at that level."
Both Charlie and Jamie McCunnie, who made his Under-21 debut against the Poles on Tuesday, returned to Tannadice on Thursday morning and went through a light training session.
Meanwhile, Craig Easton, Steven Thompson and Paul Robinson have all recovered from injury and will be fit for Saturday's clash with Motherwell at Tannadice. Derek Lilley missed training with a slight knock, but will also be ready by the weekend.
