Chile coach Jorge Sampaoli has spent much of the past four weeks sweating on the fitness of midfield Arturo Vidal, but thankfully one of the game's most formidable all-round technicians is fit and takes his place in the starting XI for tonight's Group B clash against Australia in Cuiaba.
Vidal is absolutely vital to an exciting South American side who are well-fancied to spring a surprise or two in a group also containing World Cup winners Spain and Holland, but has been in a race against time to recover from an operation on his right meniscus.
The Juventus star and much-rumoured Manchester United transfer target take his place at the head of an attacking midfield diamond tonight though despite those pre-tournament problems, with licence to get forward and hurt an Australia side who have are at least relieved from the the burden of expectation surrounding their group rivals.
Beyond the brilliant Vidal there is plenty in Chile's arsenal to worry the Socceroos though, including criminally under-rated Barcelona star Alexis Sanchez and Eduardo Vargas.
Chile: Bravo (c), Mena, Isla, Sanchez, Vidal, Valdivia, Vargas, Medel, Jara, Aranguiz, Diaz
Australia: Ryan, Franjic, Davidson, Milligan, Spiranovic, Leckie, Oar, Jedinak (c), Wilkinson, Bresciano, Cahill
Socceroos boss Ange Postecoglou has spent his short time at the helm making Australia won't sit back against Chile or anyone else though, playing a high-tempo brand of football that should make sure the neutrals have plenty to savour from game four of this summer's South American showpiece.
Experience is at the head of this system and still sees Australia rely heavily on 34-year-old Tim Cahill, while another relative veteran in Mark Bresciano has beaten a back injury to also start as Group B's less fashionable duo bid to match a quite extraordinary 5-1 clash between Holland and Spain earlier this evening.
