Spain face a critical test against Chile in the Maracana tonight following their 5-1 humiliation at the hands of Holland.
Group B is wide open in the wake of that result, and Chile must surely now fancy their chances of progression. The stylish South Americans picked up a 3-1 win over Australia in their opening game, and if they manage to take any points off Spain tonight, they'll be favourites to progress with the Netherlands heading into the final group stage match.
Spain boss Vicente Del Bosque promised changes after the Dutch debacle, and he's delivered. Iker Casillas may have feared for his place after his mistakes against the Netherlands, but he's still in goal.
Gerard Pique is out, along with Xavi as Del Bosque has instead opted for Javi Martinez of Bayern Munich and Pedro of Barcelona.
The teams are…
Spain: Casillas; Azpilicueta, Javi Martínez, Ramos, Jordi Alba; Busquets, Xabi Alonso, Iniesta; Pedro, Diego Costa and Silva
Chile: Bravo; Jara, Silva, Medel; Mena, Aránguiz, Díaz, Isla, Vidal; Vargas, Alexis Sánchez
Key man - Spain
Iker Casillas had a howler last week, but Del Bosque's kept faith and so do we. The Real Madrid keeper is a class act, and will put those mistakes behind him.
And he'll have to, because the Chileans are sure to pose a serious threat to his goal tonight. They were vibrant and forceful going forward, carving out numerous chances against the Socceroos.
The Spanish defence was torn apart against the Dutch, and getting that back on track starts with their captain.
Key man - Chile
Alexis Sanchez had an impressive season with Barcelona, and lived up to the hype in Chile's first match of the tournament.
Jordi Alba and co will be well aware of his ability but they struggled to keep up with Arjen Robben last week - Sanchez is every bit as elusive.
Chile's intense pressing style could put Spain into the same kind of trouble they suffered against the Dutch, and they'll need Sanchez to be at his best again to end Chile's winless run against Spain - they've never beaten the reigning world champions in 10 previous attempts.
