Spain enters Tuesday’s UEFA Nations League matchup on a three-match winning streak and sits atop Group 1 with nine points. Croatia, meanwhile, is 1-0-2 with three points and a -9 goal differential after suffering a 7-0 home loss to England on Saturday.

Kickoff is scheduled for 2:45 p.m. ET on October 6 at Stadion Poljud in Split.

Spain is a heavy road favorite, but the -376 moneyline offers little value. I’m looking instead at the handicap, total, and player-prop markets to identify the best betting opportunities for Tuesday’s matchup.

Odds as of October 5 at 2:37 PM ET from Kalshi .

Spain is a massive road favorite at -376, while Croatia is priced at +1150 to pull off the upset. The current prices imply a 78.99% probability of a Spain win, 7.41% for a Croatia victory, and 13.99% for a draw before accounting for the market margin.

A $10 bet on Spain at -376 would return $12.66, including $2.66 in profit. A $10 wager on Croatia at +1150 would return $125, including $115 in profit, if the hosts pull off the upset.

Spain has also attracted early support in the handicap market, with the 1.5-goal spread moving to -133. The Over 3.5 goals market has moved to +122, offering plus-money odds on a matchup with strong recent scoring trends.”

The underlying numbers point to a significant mismatch between these teams. Spain has controlled possession and generated more shots on target, while Croatia has struggled defensively. With Spain priced at -376 on the moneyline at The Score , I’m avoiding the expensive favorite and looking for more value in the handicap, total, and player-prop markets.
