Why this call

The United States, as co-hosts, carry significant home advantage playing in front of their own fans at a World Cup for the first time since 1994, which is a notable psychological and logistical boost. Their squad features quality players like Christian Pulisic (AC Milan), Weston McKennie, Tyler Adams, and Folarin Balogun, giving them strength across the pitch under Pochettino's organized system. Paraguay qualified for the World Cup but are considered a step below the USA in overall squad quality; they do have experienced players like Miguel Almirón, Antonio Sanabria, and Julio Enciso who can cause problems on the break. Head-to-head data is limited (2 matches, 4 total goals, no clear winner recorded), so little can be drawn from history. Confidence levels are moderate across the board given this is a World Cup opener with no recent results data available and Paraguay's CONMEBOL pedigree means they are capable of holding or nicking a result.
