Assistant coach Peter Houston is confident that Scotland's injured stars will be ready to face Spain.
The Scots play host to the reigning world and European champions on Tuesday in a crucial Euro 2012 qualifier.
The hosts know they will need to be at their best to take anything from Vicente Del Bosque's fearsome side, making it all the more imperative that they have a fully-fit squad from which to choose.
Craig Levein is still waiting to hear whether Tottenham full-back Alan Hutton, Wigan defender Gary Caldwell, West Brom midfielder Graham Dorrans and Rangers utility man Steven Whittaker will be available for selection, but Houston believes all four will be in the frame for a glamour encounter at Hampden Park.
"We have got four players who will train with the physio today (Sunday) and will do some work - Hutton, Caldwell, Dorrans and Whittaker," he said.
"The rest are training and we are looking forward to that training session.
"According to the physios and the doctors, the majority, if not all, of them will be available for selection. That's good news."
Meanwhile, Houston has responded to the criticism levelled at Scotland following their decision to use a 4-6-0 formation in Friday's clash with the Czech Republic.
The tactic backfired as the Czechs snatched a 1-0 win, but Houston insists the Scots have no regrets about how they approached the game.
"The only regret we've got is that we lost the game," said the Dundee United boss.
"We lost a game we were wanting to take something from, but it's over and done with now.
"We are looking forward, not looking back, there is nothing we can do about what was said and what was done. We have to look forward and what a way to look forward as we play Spain, the world champions, at Hampden.
"It's done and dusted. We would have loved to have taken something, we tried to take something, the players worked their socks off and almost got something. You have to put that to bed and start to think positively against Spain and try to take something from that match."
On the Spain fixture, Houston admits that the Scots will look to be more adventurous than they were in Prague.
He said: "It's a difficult outlook, it's a different game. We are at home so we will go and try to attack. We tried to attack in a different way against the Czech Republic."
