World Cup quarter-finalists Argentina will conclude their pool campaign against Namibia with inspiration from Diego Maradona driving them on.
Maradona watched the Pumas beat Tonga last week, and he has vowed to return if Argentina reach the semi-finals.
They face a last-eight clash against Ireland or France, and Pumas skipper Agustin Creevy has hailed Maradona's support of the team.
"He gave us a speech (after the Tonga game)," Creevy said.
"He said the whole of Argentina was dreaming with us, everyone is behind us, supporting us. That was the reason he was here - he wanted to be a part of it.
"I could never have imagined he would have been there with us. It was a beautiful surprise for all of us. He said if we reach the semi-finals he will be there. He has set us a very high goal."
