GW13 DIFFERENTIALS

Onside's top GW13 differential is Saka (ARS, 9.5% owned, 5.6 projected xP). Captain — ARS are scoring freely. 15% haul chance. Other differentials: Matheus N. (1.5% owned), Tarkowski (8.6% owned), Donnarumma (8.2% owned).

In FPL, a differential is a player owned by fewer than 10–15% of managers. Owning a differential who scores big gives a huge rank boost because the majority of managers miss the points. Onside's DIFFERENTIAL tag identifies players with ownership below 15% who also carry a BUY or STRONG_BUY action rating from the v5 engine — meaning the engine thinks they're genuinely undervalued, not just low-owned for bad reasons.

A -4 point transfer hit needs a minimum 4-point swing to break even. For a differential to justify a hit, the engine should project them at 8+ expected points (since the hit costs 4, you need 4 more than a bench player gives). Differentials are best transferred in for free on wildcards or when your squad has a glaring weakness — not as speculative hits. Check the GW13 full guide for the highest-confidence buy options.

The Fantasy Premier League GW13 deadline is Wed 2 Dec, 18:30 UK time. Make sure your differential selections and transfers are confirmed before this time.

Differentials are highest value when you're chasing rank mid-season or in mini-leagues with points gaps. A 15% owned player who scores or assists gives you a 6–9 point swing vs the field compared to a 50%+ template player hitting the same return. Use these picks when your template is strong — not to replace reliable assets, but to add upside beside them.
