Argentina coach Diego Maradona said on Monday that he believes greater emphasis should be placed on fair play at this summer's World Cup.

The 49-year-old's side won both their opening two matches, beating Nigeria 1-0 and South Korea 4-1, but he still feels the officials need to be doing more.

"We all want fair play," he said to the soccernet.com. "I understand that the referee may make a mistake but when (Argentina captain Javier) Mascherano, for instance, gets a card and the Korean player kicks out and gets nothing, no card, then sometimes as a coach you have doubts.

"This is football and not kung fu fighting, so I don't think yet we've seen the fair play we want to see."

Maradona was also asked his opinion on Luis Fabiano's controversial second goal for Brazil in Sunday night's 3-1 win over Cote d'Ivoire.

Luis Fabiano appeared to use his arm twice to control the ball in the build-up to his goal, which put Brazil 2-0 up five minutes after halftime, and said after the match it was a goal scored by the 'Hand of God'.

Asked to comment, Maradona said, laughing; "No, this one hit his arm. It's pretty obvious - the ball even hit his arm twice."
