Nigeria coach Stephen Keshi has admitted he doesn't know a lot about Iran as they prepare to face each other in their first game of the World Cup.
The Asian country are appearing in just their fourth World Cup finals, having crashed out at the group stages with a solitary point in their most recent outing in 2006.
And Keshi has admitted that Iran, who are ranked 43rd in the Fifa world rankings, are a largely unknown quantity for him and his staff, but is mindful of the experience of their coach, Carlos Queiroz.
"We have to go out with everything that we have," he said at a press conference. "They have a very good coach and I'm sure they also have some quality players. We don't know Iran very well, but we'll see them on Monday. I think an experienced coach is their biggest weapon. He's well experienced, he knows the game well.
"For me, scoring a lot of goals is not the most important thing. I want us to score and reach the knockout stages. If we score every game, I'll kiss each and every journalist in here..."
While the 52-year-old doesn't know what to expect from his side's first opponents, he insists they cannot afford to underestimate them.
"For the Iran game we have to be focused. We have to concentrate and do our job. We're not going to take Iran lightly because they're not going to take us lightly."
