Despite Holland having scored plenty of goals in this tournament, they have had a quite defensive approach to games. Maybe highlighted by the fact that their highest-scoring game was the one where the opponent had the ball more and were expected to have more play. In games against presumably weaker opposition, their approach has often been to pass the ball around and try to tempt the opposition higher up, in order for Holland to take them on the counter.
The interesting twist here is that Argentina have so far appeared to be not very different from that. Defensively, they have been in control for most of the time (except short periods against Iran and Switzerland), but they have seemed to lack creativity up front. A shame, as they have more players than Messi who should be capable of creating something.
We can be facing a game where neither team will be comfortable with being the team who have the ball more, because they fear the counter-attacking capabilities of the opponents. I predict a low-scoring game, going to extra time.
