You are Scotland boss Pocognoli - what would you do?

Pocognoli has settled on a 3-4-2-1 formation but the approach is far from convincing, with a lack of threat from the flanks among the issues facing the Belgian.On the left, there are question marks about the quality of Andy Robertson's deliveries in recent times. On the right, natural winger Ben Gannon-Doak has looked entirely uncomfortable.Would it be more effective to use them in their regular club positions? Pocognoli has intimated that he is not married to the system, telling BBC Scotland he will try "to find the best shape to make the players shine on the pitch."I always try to adapt to my team. I think the shape that we play is the best shape to fit the best quality of the team."If he is going to stick with three at the back, does Kieran Tierney perhaps have a better delivery than Robertson? Is a three at the back system the only way to accommodate both? Either way, Robertson is going to start and he's going to become the nation's most capped player.Full-backs Aaron Hickey and Nathan Patterson are certainly more used to defending than Gannon-Doak, but can they be relied upon to provide a cutting edge in the final third?On a largely-exasperating evening, Gannon-Doak did earn the penalty that brought victory on Friday. If the boss sticks to his guns, could his speed and direct running be utilised behind a striker instead of out wide?Speaking of Serie A Scots, Bologna midfielder Lewis Ferguson has played every single minute under Pocognoli - the only outfield player to achieve that feat.Billy Gilmour has started next to Ferguson in midfield in all of five of those games, with the head coach keen for the Napoli man to play a little higher up the pitch instead of in the deep-lying role he played under Steve Clarke.Again, there have been questions about the effectiveness of the pair. Ferguson was arguably Scotland's best player in a poor World Cup display and his ball-winning prowess might suit the Switzerland game.But no player in the English Premier League has won the ball back more in the opposition half than Ryan Christie.The former Inverness, Aberdeen and Celtic midfielder was more known for his attacking intent but over the last 18 months, he has been moved to a deeper, more central role in a flying Bournemouth team.He recently captained the Cherries to a 3-0 win over AC Milan, has started of three of the last four in Bournemouth's unbeaten league run, and began in the 3-0 win over McGinn's Aston Villa in the League Cup.He reached his 75th cap coming off the bench against North Macedonia but has started just once under Pocognoli, in the 2-1 loss against Slovenia.Is there a place for him in this team? Who would drop out if that were the case? Or is there a way for Pocognoli to name all five big midfielder - including McGinn and McTominay - at once?
