Objective analysis of each team's fundamentals (for viewing reference only, not a prediction of win or loss)

1. Spain vs Saudi Arabia
Spain has a balanced lineup and a mature passing and control system, ranked high in the world; Saudi Arabia mainly relies on counterattacks, with weaker physical confrontation, drew in the first round, and urgently needs to score points to stabilize their qualification situation.

2. Belgium vs Iran
Belgium has abundant front-line star reserves, with a perfect record against Iran historically; Iran focuses on dense defense, has strong willpower, and is good at relying on set-piece attacks, likely to defend stubbornly and seek a draw for points.

3. Uruguay vs Cape Verde
Uruguay has a tough defense and experienced forwards; Cape Verde is a newcomer with insufficient tournament experience, and there is a clear gap in overall squad depth.

4. New Zealand vs Egypt
New Zealand plays a high aerial and target man tactic, drew with Iran in the first round; Egypt is eager for their first World Cup victory in history, with an advantage in midfield passing and control, both teams have similar strength, and the outcome is highly uncertain.
