It was a goal deserving of winning the contest, although an obvious lack of skill in the match once again raised question marks over the validity of the competition in its present form.

For Al Ahly it was a disappointing end to a tournament that has finished way below their expectations.

As the dominant force in Africa over recent seasons, the Egyptians were expecting to reach the semi-finals and even run LDU Quito close in the battle to reach Sunday's decider.

But their lack of a killer punch has been exposed and after surrendering a two-goal lead to Pachuca on Sunday they failed to force their way back into this contest too, after falling behind to Cristiano's early strike, despite dominating possession.

In contrast, the game in Australia continues to grow, with Adelaide's performances giving encouragement to the newly-expanded A-League.

With many of Australia's star names earning their living in Europe it will be gratifying that Adelaide have finished fifth, showing dramatic improvement in a single goal quarter-final loss to Gamba Osaka, who put five past them in last month's Asian Champions League Final.

They held Al Ahly fairly comfortably once Cristiano had put them in front in fine style.

Picking the ball up on Adelaide's left, the Brazilian embarked on a solo burst which took him within shooting range and he duly fired a superb effort past Amir Abdelhamid.

Indeed, the Australians might have had a second through Sasa Ognenovski but this time Abdelhamid made a fine save.

Al Ahly's best chance of an equaliser came eight minutes from time, only for Eugene Galekovic's flying stop to deny Mohammed Barakat.

The win earns Adelaide a US$1.5million prizemoney purse, worth about AU$2.1million. Al Ahly still picked up US$1million for their sixth place.
