Strachan must rebuild

           Scotland had somehow turned the game around, having spent the opening half-hour on the back foot, and with a goal advantage against a Wales side now without their talisman Gareth Bale, victory should have been achievable.What Friday night's showing proves, beyond reasonable doubt, is that Scotland's position at the bottom of Group A is no fluke. The absence of Darren Fletcher and Scott Brown was keenly felt, with the central midfield of James McArthur and Graeme Dorrans unable to keep possession or adequately break up the Welsh attacks.The early loss of Steven Fletcher also robbed Strachan of a key talent, but it was in defence that the Scots looked desperately short of confidence, with the new central pairing of Gary Caldwell and Grant Hanley failing to gel.But a rash decision by Snodgrass to dive into an almost irretrievable situation and some static defending to allow Andy King and Hal Robson-Kanu to carve out the winner leaves the Scots no better off than when they last left the Hampden pitch after the draw with Macedonia.  Serbia, Scotland's next opponents, are two points above the Scots but there is little to suggest - either from Friday's game or the earlier draw between the sides at Hampden - that Strachan's men will move above them and off the foot of the table on Tuesday.Scotland's only remaining home games are against the top two teams in the group - Belgium and Croatia - so the likelihood of a victory in the group is now seriously dwindling.
