Four La Liga fixtures hit the card on Tuesday April 21. We break down the best parlay combinations and value spots using live market odds from FanDuel.
La Liga Tuesday Parlay Guide - April 21, 2026
Tuesday's La Liga slate serves up four fixtures with some genuinely interesting odds across the board. From Real Madrid hosting rock-bottom Alavés to a tightly contested Mallorca vs Valencia relegation scrap, there's plenty to work with here. All odds are sourced live from FanDuel. Let's break it down and build some smart parlay combinations.
Game-by-Game Analysis
Mallorca vs Valencia - 18:00 UTC
This is a genuine six-pointer in the relegation battle. Mallorca sit 15th on 34 points, just one ahead of Valencia in 14th on 35. Both sides are fighting for their Primera Division lives, which makes this match unpredictable but crucial. FanDuel prices the home win at +155, the draw at +220, and Valencia at +200.
With both teams desperate for points, this has all the hallmarks of a tight, cagey affair. Valencia have been inconsistent - 9 wins, 8 draws, and 14 losses - while Mallorca's home form is their strongest asset in what has been a difficult season overall. The draw at +220 looks like a genuine value option here given how evenly matched these two are in the standings. That's an implied probability of roughly 31% - we'd put the real chance closer to 35-38%.
Best Bet: Draw +220 (FanDuel) - Value Flag
Athletic Bilbao vs CA Osasuna - 18:00 UTC
This is a fascinating match-up between two sides sitting close together in mid-table. Athletic Bilbao are 12th on 38 points with 11 wins but a concerning 15 losses. Osasuna sit 9th on 39 points with 10 wins and 9 draws - a steadier, more resolute team on paper. FanDuel has Athletic as favorites at -105, with the draw at +240 and Osasuna at +360.
The home price of -105 for Athletic is marginal at best given they're only a point behind Osasuna in the table. Osasuna's draw tendency - 9 in 31 games - is worth noting. The draw at +240 is another potential value spot. However, Athletic's home advantage in a sold-out San Mamés is a real factor, so backing the home win at just under evens isn't unreasonable in a parlay context.
Best Bet: Athletic Bilbao -105 (FanDuel) for parlay inclusion
Girona vs Real Betis - 20:30 UTC
Girona sit 11th on 38 points, while Real Betis are 5th on 46 points with 11 wins and a league-high 13 draws. Betis are clearly the better side this season and still in contention for European spots, while Girona's -12 goal difference tells the story of a side that has struggled badly compared to their Champions League campaign of a couple of seasons ago.
FanDuel prices Girona at +160, the draw at +240, and Betis at +185. Betis at +185 looks generous here for a side sitting 8 points clear of Girona in the table. The implied probability on Betis is just under 35% - we'd suggest the true probability is closer to 42-45% given the standings gap. This is our strongest value flag of the night.
Best Bet: Real Betis +185 (FanDuel) - Strong Value Flag
Real Madrid vs Alavés - 20:30 UTC
Second-place Real Madrid host Deportivo Alavés, who sit 17th on just 33 points and are still not mathematically safe from relegation. Madrid on 70 points are chasing Barcelona at the top, and with a +36 goal difference, they have been clinical all season despite their occasional inconsistency. FanDuel makes them massive favorites at -345, with the draw at +500 and Alavés at a wild +950.
The price is short on Madrid, but at -345 this is one of the safest picks on the slate. In parlay terms, converting -345 into a combined ticket is exactly how you justify including heavy favorites. Alavés at +950 is a mouthwatering long shot if you're feeling adventurous, but realistically this game has Real Madrid win written all over it.
Best Bet: Real Madrid -345 (FanDuel) as parlay anchor
Recommended Parlay Combinations
Parlay 1 - The Safe Double (Moderate Return)
- Real Madrid to win - FanDuel -345
- Real Betis to win - FanDuel +185
Combined odds: approximately +110 to +120. This is your value-focused combination. Madrid are near-certainties at home against a relegation-threatened Alavés, and pairing them with Betis - who we believe are underpriced at +185 against a struggling Girona - gives you a real-money return on a sensible two-leg ticket.
Parlay 2 - The Value Double (Higher Return)
- Real Betis to win - FanDuel +185
- Mallorca vs Valencia Draw - FanDuel +220
Combined odds: approximately +610 to +630. Both legs are flagged as value picks against their implied probabilities. A draw in the Mallorca-Valencia relegation battle is statistically well-supported, and Betis winning in Girona completes a tidy ticket with a strong payout for modest stakes.
Parlay 3 - The Three-Leg Accumulator (Big Return)
- Real Madrid to win - FanDuel -345
- Athletic Bilbao to win - FanDuel -105
- Real Betis to win - FanDuel +185
Combined odds: approximately +280 to +300. Three reasonable favorites - two at home - anchored by Madrid's dominant home form. Athletic at just under evens at San Mamés adds modest but justifiable weight, and Betis rounds it off as our value pick of the evening. A solid three-legger with a meaningful return without going too exotic.
Value Recap
- Real Betis +185 (FanDuel) - Implied prob ~35%, estimated true prob ~43%. Best value on the slate.
- Mallorca vs Valencia Draw +220 (FanDuel) - Implied prob ~31%, estimated true prob ~37%. Good value in a derby-like relegation scrap.
- Alavés +950 (FanDuel) - Long shot only. Not recommended in parlays, but noted for single-unit flutter bettors.
Tuesday's La Liga card is headlined by that blockbuster Madrid fixture, but the real parlay value lies in backing Betis and the Mallorca-Valencia stalemate. Build smart, stake sensibly, and let the odds do the work.
