Spain boss Vicente del Bosque believes Scotland's strength in unity - rather than their star players - will be their biggest weapon at Hampden.
Spain will be aiming to strengthen their grasp on top spot in their Euro 2012 qualifying group on Tuesday night, while the Scots will be hoping to avoid another defeat following a 1-0 reverse against Czech Republic.
The build-up to Friday's clash in Prague was dominated by headlines sparked by Craig Levein's decision to axe in-form striker Kenny Miller in favour of an ultra-defensive system that ultimately failed to prevent the first loss of the campaign.
The Rangers forward is one of Scotland's best players as far as Del Bosque is concerned, but he believes a group effort is most likely to deliver a result for the home nation.
"The strength of Scotland has always been their team and group of players and how they play as a group," he said. "We know they've got excellent individuals, people like Alan Hutton and Darren Fletcher, who both play south of the border, and Kenny Miller, who plays with Rangers.
"We also know they've got one or two important injuries and people missing, like Barry Robson and James McFadden, who are important individuals for them but, as I say, it's the strength in unity they've got as a team which is Scotland's thing."
Del Bosque is well aware that every team will raise their game against Spain following their success at the World Cup this summer, and knows Scotland will be no different.
"It's a special game for every opponent that we play now but it's something we are used to now and we can deal with it," he said. "This is another challenge, every match is a challenge. Players always look forward - not back at what they have achieved."
