With Brazil and Mexico having both progressed to four points as a result of their goalless draw in Fortaleza on Tuesday night, the pressure is on for the other two teams in the pool.

Defeat for either at the Arena Amazonia in what will be the first-ever meeting between the two nations would mean failure to qualify for the last 16 of the tournament.

Cameroon, who lost 1-0 to Mexico last Friday, are likely to have to cope without striker Samuel Eto'o, who is nursing a knee injury sustained in the closing stages of Chelsea's season.

The 33-year-old has not been ruled out however, having told Cameroon media on Tuesday: "I hope the gods grant me a miracle and that I am able to defend my country."

Eto'o played the full 90 minutes in Natal and could be replaced by Fenerbahce frontman Pierre Webo, although Vincent Aboubakar - who hit 16 goals for Lorient in Ligue 1 last season - is also pushing to get the nod in Volker Finke's starting line-up. Former Aston Villa man Jean Makoun may slot into a defensive midfield berth after shaking off an ankle injury.

Mario Mandzukic is back for Croatia after serving a one-match ban for the 3-1 tournament-opener defeat by Brazil in Sao Paulo. Nikica Jelavic is expected to make way for Mandzukic, who hit 18 goals for Bayern Munich in the Bundesliga last season.

Luka Modric has shaken off a foot injury and will start the game for Niko Kovac's side.

Versatile left-sided player Danijel Pranjic is also available again to Kovac after an ankle injury kept him out on Thursday. Speaking to FIFA.com on the benefit of Mandzukic's return, he said: "He definitely makes us stronger and you can't replace him like-for-like.

"He's prepared to go out and ‘die’ for the cause. Lajic [Jelavic] did really well against Brazil, but Mario is Mario. We need him. We’re a totally different team without him."
