This week, Sean Wallace tells us what he learned about Aberdeen's new attacker Callum Roberts from former Killie boss Lee Clark, while we also ask if Hayden Coulson is going to be the Dons' main left-back this term. Is there enough depth on the left side of defence generally after this week's departures? There are certainly defensive conundrums and questions over who to start in attack at Celtic in Sunday's Premiership opener - Who replaces Liam Scales? Miovski or Ramirez? Does Roberts get a starting debut? Meanwhile, Ross County's attack are flying going into their Hearts clash, while Inverness step into the unknown v Queen’s Park in what looks like an early banana skin for the Championship hopefuls. Plus, Cove Rangers and Peterhead still looking really light – or even lighter - two days before their league campaigns get under way, as Gavin Price tries to banish Elgin’s tendency for second half switch-offs.
