Mark Wotte has told Scotland fans that no manager could instantly turn the national team into World Cup standard as he warned the work he is doing at youth level will take "four to six years" to come to fruition.
The Scottish Football Association's performance director believes expectations are too high among Scotland fans as their wait for qualification for a major tournament looks set to extend to at least 18 years.
Defeats to Wales and Belgium left Scotland bottom of their World Cup qualification group and leaves manager Craig Levein in a highly precarious position after claiming two points from four matches.
SFA chief executive Stewart Regan has confirmed talks will take place over Scotland's performances, although it is understood they will not begin until a week on Monday at the earliest.
Wotte gave his assessment on Thursday and claimed the standard of players Levein is working with means it is too simplistic to blame the manager.
"I see a lot of desire in Scotland to be part of major tournaments but sometimes the desire and expectations are a little bit mixed up," the Dutchman said.
"It's a really tough group for Scotland because we are not better than Belgium, that's for sure.
"Croatia are a very decent side so it leaves us with Serbia, Macedonia and Wales to be the number three, which is not good enough if you want to qualify, but maybe that's realistic.
"I'm looking at it from another perspective from the fans. We have to be realistic and say how good is this squad and how good do you have to be to qualify for the World Cup?"
