First, let’s look at the tone of the Netherlands’ match. The Oranje are comfortably sitting atop the group, so they are unlikely to go all out purely to pad the stats. That would not fit their usual style, but it does not mean they will sit back, slow the tempo, and play conservatively through to the end. In this match, they are likely to rotate half of their starting XI, and those substitutes are precisely the group most eager to make an impression on the pitch. To fight for a better place in the pecking order for the knockout stage, they will be more willing to take on defenders and make forward runs in attack. With a relaxed mindset but also a competitive edge, they may actually be more likely than a full-strength side to produce smoother combinations and create more open scoring chances. Their possession-based attacking framework will not be compromised in the slightest.
Now look at Tunisia’s motivation. The North African side still have a chance of advancing, so there is no way they will sit deep and defend for their lives in this match. They will certainly push forward proactively in search of attacking opportunities. Their wing play and set-piece threat are already dangerous, and against a Netherlands defense that may lack cohesion after rotation, they have every chance of creating real danger and even scoring. At the same time, the space they leave behind by pushing up is exactly the kind of situation the Netherlands are best at exploiting on the counterattack. The tempo of transitions will be accelerated immediately, and the midfield is unlikely to become a long, grinding battle of attrition.
Data-model projections show that the combined expected goals (xG) for both sides will remain steadily in the 3.4-3.6 range, with both goals under sustained pressure throughout the match. This will not be a one-sided rout, but an open contest with chances at both ends, where both teams can find success in attack. The probability of total goals going over the 3.25 line is clearly in the favorable range.
