The key talking points from Pocognoli's bold Scotland squad

As for the backline, the new Scotland boss has predominantly played with a back three throughout his coaching career at both Union Saint-Gilloise and Monaco.He insists on his teams being aggressive in and out of possession, so will want defenders capable of picking brave passes but also with the pace to cover big distances when playing a high line.Scott McKenna, Jack Hendry and Kieran Tierney all have experience of playing in a back three under Steve Clarke, albeit the approach will differ under Pocognoli. Captain Andy Robertson also clocked up a lot of minutes at left wing-back.Aaron Hickey, Nathan Patterson and young Colby Donovan, who has impressed Pocognoli "but needs to improve on things like every young lad", are options for the opposite flank.Uncapped trio Luis Binks, Stephen Welsh and Luke Graham add more depth at centre-back.Brondby captain Binks, who qualifies for Scotland through a grandparent, has had an interesting career. "The feeling and the timing about him was right," Pocognoli said of the former Bologna and Como man.At the age of 25, the left-footed centre-back has already played in the MLS, Serie A, English Championship and now Denmark's top tier.Meanwhile, Stoke's Graham - also left-footed - enjoyed a breakthrough spell at Dundee last season and continues to excel in England's second division, along with Swansea's Welsh, who proved he could thrive in a possession-based Motherwell side last term.While Ben Gannon-Doak, Findlay Curtis and McPake offer options in attacking wide areas, there is a centre-forward spot up for grabs in the absence of injured pair Che Adams and Lawrence Shankland, plus the omission of Lyndon Dykes.A free-scoring spell in Sweden earned Robbie Ure the number nine shirt at Sevilla, Oli McBurnie and his Hull team have made an impressive return to the Premier League and Sassuolo's Kieron Bowie scored in a win against Juventus on Sunday."Players who are performing well are in the new pathway," Pocognoli said when asked about Rangers academy product Ure, who is yet to score since his switch to La Liga."Robbie is adapting well to La Liga. He's put in some good performances, but he maybe needs to adapt to the intensity. Being selected gives him an opportunity."On the return of McBurnie, who has received his first Scotland call-up in five years, he added: "It's regarding style of play, playing time and performance. I have to start on a new journey, a new book and it's a new opportunity for some players."The head coach also spoke of his desire to mix youth with the "DNA and heritage" of his squad, evidenced by the inclusion of teenage James Wilson, who is showing signs of fulfilling his serious potential at Hearts.By the end of the first week in October the Tartan Army, many of whom have been calling for what Pocognoli is preaching to deliver, will have a clearer idea of what that formula is going to look like on the grass, with a fascinating four-match window approaching.
