​On a dismal night at Hampden when Scotland failed to ask enough questions of Slovenia, there are one or two that could be posed to new boss Sebastien Pocognoli and his players.We knew Pocognoli was a disciple of three at the back – the issue being whether he was rigid or flexible in his philosophy, whether he was a bit of an ideologue or a coach capable of changing things on the hoof.Well, he changed it, that’s for sure. Maybe not early as he should have, but at 1-1, and then when Slovenia took a deserved 2-1 lead, Pocognoli switched formation and personnel, not out of design but out of desperation, you felt. He hurled players on in a bid to take a point; strikers, wingers, kitchen-sink stuff. Indiscriminate and messy. Scotland never really got out of the blocks. They got what they deserved.So to the questions. Where did this turkey of a performance come from? As early as the 13th minute there were signs of a rough night when Slovenia got in behind and Adam Cerin’s shot had to be blocked by Jack Hendry. Concerning.’Outfought’ and ‘not good enough’ – Robertson on Scotland defeatSlovenia come from behind to beat ramshackle Scotland at HampdenHow promotion, relegation and knockouts work in Nations LeagueIt got a touch nervy as the visitors knocked it about, trying to work it into all the space that Scotland were affording them. Hampden was deathly quiet. Then Ryan Christie scored and it stirred, only to fall into a slumber again.The trouble at the back was revisited soon after, Andy Roberton having to make a lung-busting effort to throw himself in front of a point-blank shot from Zan Vipotnik after Hendry was caught dozing.The issues were obvious. Can the back three, so badly exposed by Slovenia, be long for this world when the opposition is decent? Why did all that acreage of space open out wide and through the middle? Slovenia were licking their lips for most of the night. They were clever and creative and should have won by more.Why did Scotland’s lauded midfield look so overrun? Seconds into the second half, Slovenia went straight through the middle again. Was anybody taking note of the warning signs? Where was the intent and urgency? Where was the accuracy and the width? Where were the chances? Where were the bodies in the box supporting the frontman and the pressing game?How could Slovenia go from being thoroughly outplayed by Scotland in the second half in Ljubljana to being so superior in Glasgow? Aljosa Matko’s equaliser started with a Scotland throw-in. Danijel Sturm’s chance that should have made it 2-1 three minutes later came on the back of Ben Gannon-Doak staying miles up the pitch oblivious to Sturm’s danger. Angus Gunn didn’t exactly cover himself in glory, either.The goal that we thought had made it 2-1 was disallowed – correctly – for offside, but the build-up was more of the same. Before Matko banged it past Gunn, Slovenia won one aerial duel and then another. Weak, weak, weak.That second goal did come, as everybody suspected it w
