Brazil hope to turn on the style against Cameroon

Brazil have failed to convince in their opening matches, grinding out a 3-1 win over Croatia before toiling to a 0-0 draw with Mexico in Group A.
However a win over an eliminated Cameroon could give them useful momentum heading into the last 16, where they would face Chile or the Netherlands.
Brazil captain Thiago Silva acknowledged the hosts had not yet fired on all cylinders as they chase a record sixth World Cup crown.
"We want to show we are a good team and can play collectively in the best manner possible," Thiago said.
"In recent games we have had some problems, but that is normal at a World Cup."
The other final match in Group A sees Mexico and Croatia duel in Recife to determine who else advances, most likely in second place.
In Group B meanwhile, the Netherlands face Chile in Sao Paulo in a match to decide who tops the standings -- and most likely avoids the possibility of meeting Brazil in the last 16.
A draw will be good enough for the Dutch, who enjoy a vastly superior goal difference after their 5-1 thrashing of Spain and 3-2 win over Australia.
Spain, dumped out of the competition after consecutive defeats to the Dutch and Chile, play Australia in a dead rubber where little more than pride is at stake.
Monday's final round of group fixtures get under way with several fancied teams facing the prospect of an early elimination.
Portugal and Cristiano Ronaldo's chances of surviving into the second round were left hanging by a slender thread after their 2-2 draw with the United States on Sunday.
Although Portugal fought back to claim a point with a stoppage time equaliser just seconds from the final whistle, Germany and the United States remain in pole position to qualify from Group G.
A draw between the Americans and Germans on Thursday in Recife would secure safe passage to both sides -- and see Portugal and Ghana knocked out.
The scenario has revived memories of the notorious 1982 game between West Germany and Austria, when the two sides effectively conspired to hand Germany a 1-0 victory which saw both sides go through at the expense of Algeria.
US coach Jurgen Klinsmann has said there is no chance of a similar controversy unfolding when his team face Germany.
"You’re talking about a game that is decades ago," Klinsmann said in reference to the 1982 game.
"That is only a part of Germany’s history and not part of the United States’s history. I think if you look at the past of the US team, we always try to make things happen.
"We have that fighting spirit, and we give everything in every game," said Klinsmann.
"We will go to Recife and we will give everything to beat Germany. That is our goal."
