Perfection is hard to attain in football. Argentina coach Alejandro Sabella says that's what his team needs to achieve to have a chance of beating Germany in the World Cup final on Sunday.
Describing the Germans as "very powerful" rivals physically, mentally and tactically, Sabella on Saturday said there's no room for error for Argentina.
Sabella says: "We must play a perfect game."
The coach said injured winger Angel Di Maria's condition was improving, though it was still unclear whether he would be fit to play on Sunday.
He also dismissed a question about whether he would step down as Argentina coach after the match, saying the issue was "irrelevant" and that he was only thinking about the final.
