Scotland's World Cup hopes hinge on mirroring Cape Verde's defensive masterclass against Spain

The Tartan Army's wonderful takeover of Boston has been the story of the World Cup so far, but on the field it was Cape Verde's stunning draw against European champions Spain that sent shockwaves through the tournament.

In their debut match at the World Cup, the Africans – ranked 67 in the world and with a population of less than 500,000 people – put in a heroic defensive display to thwart a star-studded Spanish side tipped by many to become world champions for a second time.

Scotland know if they can mirror Cape Verde's result and take a point from Friday's Group C meeting with Morocco at the Boston Stadium, they will be all but guaranteed a passage into the knockout stages for the very first time at a major tournament.

So what lessons can the Scots take from Cape Verde's remarkable display?

Grant Hanley and Jack Hendry showed up well in Scotland's opening game, both making vital interventions as Haiti came on strong in search of an equaliser after John McGinn's strike.

Whether head coach Steve Clarke retains that centre-back pairing or reintroduces the fit again Scott McKenna – he could switch to a back five and play them all – the entire Scottish defensive unit will need to show the ferocious desire to protect their goal that Cape Verde did so impressively against the Spanish.

"One of the big things Cape Verde work at, and the manager has talked about it, is the culture of the country itself and making sure that everybody buys into that. If you do that, everyone will work for each other," said former Scotland winger Pat Nevin after covering the match at Atlanta Stadium for BBC Radio 5 Live.

"Boy, what a sight of players working for each other we saw. They spent the vast majority of the game on their own 18-yard line, not all of it, and when they broke, they were brave and they broke in numbers.

"To do that and keep that level of concentration, you don't do that if you're a bunch of individuals, you only do that if you're a group, if you're a team, if you believe in each other. And it shone through.

"I watched Sidny Cabral start the game and thought, 'oh, my goodness, there's a disaster waiting to happen' because of the way he was tackling - but he got every one of them right.

"You look at Diney Borges, again, he looked like he was a kitten at the start of the game. By the end of the game, he was a lion."

Former Scotland defender Willie Miller was similarly impressed with Cape Verde's defensive discipline and highlighted the concentration levels to shut Spain down, something Scotland will undoubtedly have to display against the attacking threats of Morocco.

"Cape Verde had the 4-5-1 formation, they defended deep, they closed the opposition down very quickly," said Miller, who played at the at the 1982 and 1986 World Cups.

"Sometimes you have to have a little bit of good fortune. The goalkeeper was in such good form as well and didn't look like he was going to lose anything but it's a long time to go with that formation.

"You tend to get mentally fatigued when you're doing most of your work without the ball and I think that could have been a problem - but it wasn't a problem for Cape Verde.

"They had organisation, the team spirit, the shape, a goalkeeper in fine form, restricting any space between your defence, midfield and forwards, and then just had that belief that they could get it over the line and get the draw. That's what we need against Morocco."

While defensive organisation and resilience was the foundation of Cape Verde's performance, they still managed to retain some semblance of attacking threat on the counter-attack, especially late in the game, to relieve some of the pressure at the back.

They might even have snatched a famous victory, with defender Borges going close with a late header and a couple of late counters threatening to catch Spain out as they poured forward looking for a winner.

Scotland will need to give the Moroccan back-line something to think about if they are to avoid a dangerous pattern of being pinned in on the edge of their own box.

Former Scotland winger Neil McCann believes the presence of Ben Gannon-Doak, a standout performer against Haiti, will be crucial in getting the Scots up the pitch.

"Ben Gannon-Doak is obviously a very big weapon for Scotland in terms of how he eliminates people in the wide area," McCann said.

"He's shown in his Scotland career already that he can play off the left, off the right, and standing people up and just going past them like they're not there.

"The one thing I want to see him work on is his final ball. Getting past people generally isn't a problem. It's what you do once you're in that position.

"It doesn't matter who he's playing against, whether it's [Denmark's Patrick] Dorgu, whether it's Achraf Hakimi against Morocco, I still think he'll create chances."
