One of the following five players has to be left out of the team: Ronaldo, Adriano, Ronaldinho, Kaka, Robinho.

So far, coach Parreira has been spared having to make the decision.

Ronaldo made it for him by asking to be rested from the Confederations Cup in June, then Ronaldinho was suspended from Sunday's 5-0 win over Chile.

The recent emergence of Robinho and Adriano as world class players has left Parreira in a quandary.

Usually seen as a somewhat unadventurous type, Parreira reshuffled his side earlier this year and effectively fielded four strikers to accommodate as many of Brazil's world class forwards as possible.

Playing all five together -- the so-called Magic Quintet -- is not regarded feasible by Parreira as it would leave the team too vulnerable at the back, although some commentators are suggesting he should give it a go.

Until Sunday, Adriano and Robinho would still have been favourites to sit out the start.

But, as at last year's Copa America when he finished as top scorer with seven goals and this year's Confederations Cup when he scored five, Adriano grabbed his chance with both hands by blasting a hat-trick.

The victory over Chile secured the World Cup holders a place in next year's finals.

"The important thing was that we qualified," Adriano said. "I hope to continue like this, keep working away quietly and slowly but surely I'll get there."

Robinho furthered his claim by scoring one himself and laid on two of Adriano's goals.

Adriano's hat-trick, his second for Brazil, took his international tally to 20 in 28 matches.

Once described as a horse by Parreira because of his sheer physical strength, Adriano has notched seven goals in his last four outings.

On the other hand, Ronaldo, his striking partner on Sunday, completed his sixth international without hitting the target.

Ronaldo, whose last goal was against Venezuela in October 2004, went off at halftime with a minor muscle problem and must now be wondering if he could be the victim.

The Phenomenal One has already expressed regret at his decision to skip the Confederations Cup, when Adriano took his place and terrorised opposing defences.

"I don't want to be rested again, I always want to be with the Brazil team," he confessed last week.

Robinho said he had no idea who he would take out.

"There are five excellent players there and it's the sort of problem any coach would like to have," he said.

"It's Parreira's job to decide but whoever he chooses, Brazil is ready for anyone."
