George Burley believes his Scotland squad for two crucial 2010 World Cup qualifiers is as strong as possible.
Impending dates with Holland and Iceland could go a long way to determining how Group Nine unfolds.
It is therefore imperative that Scotland take positive results from an away date with the Dutch on 28th March and a Hampden Park clash with Iceland on 1st April.
Burley has seen his plans partially disrupted by injury, but has been able to bring the likes of Tottenham full-back Alan Hutton back into the fold after a long-term injury.
"He has been training for the last week and I spoke to Harry Redknapp and Alan," said Burley.
"He has a reserve game on Monday, which is ideal for Alan to play in and assess his fitness.
"We've not closed the door - he's in the squad. We will keep our fingers crossed the game goes well and then he will join us."
Burley has also handed Gary Teale a first call-up in 12 months, but believes the Derby winger is ready to make the step up.
He said: "There are no experiments. We have two very important World Cup games and it's a settled squad. The only new addition is Gary Teale.
"He has been in excellent form with Derby County this season and he has pushed his way back into the squad. He gives us pace, which we have maybe been lacking, and he is a natural wide player."
The former Southampton and Ipswich boss also admitted that he considered selecting Rangers' teenage prodigy John Fleck, before deciding to let the youngster cut his teeth in the U21 side.
"It's progression," said Burley.
"At 17, to get into the Under-21 squad is tremendous. His time will come."
