As important as the man who provides the header is the one who gets in the cross. And Paraguay will be pleased that the goals against Sweden came from two very different supply lines.
The first was from open play, from a break down the left and wonderful cross by Jorge Campos. Shrewdly recalled by coach Cesare Maldini, Campos is a flying winger who fits perfectly into a counter attacking game.
He will probably be used as a substitute in the World Cup, although his performance against Sweden makes it harder to leave him out.
Paraguay's second goal was set up by a free kick, superbly struck by
Paraguay's right back is David Beckham's main rival for the owner of the world's best right-footed cross. His corners and free kicks
are hit with venom, and set up a steady stream of chances.
As shown against Sweden, with skilled supply and proficient heading Paraguay are always capable of snatching a goal from nowhere. But the other lesson of the Sweden game is that, compared with France 98, Paraguay are now more likely to let goals in.
Defending has never been Arce's speciality, and now, aged 31, injuries have slowed him down and made him more vulnerable.
