Both teams to score betting explained

Both teams to score settles Yes when each side scores at least one goal in regulation time, and No otherwise. Own goals count for the team credited with the goal. Extra time and penalties are excluded unless the book explicitly states a 120-minute market.

The appeal is that the result is irrelevant: a 1-1 draw and a 4-3 thriller settle identically. That independence from the match winner is why BTTS is the most popular non-1X2 market in Nigeria and why it appears on almost every accumulator coupon.

A fair BTTS price comes from two independent Poisson distributions. If the home side is expected to score 1.6 goals and the away side 1.1, the chance the home team fails to score is e^-1.6 = 0.202 and the chance the away side fails is e^-1.1 = 0.333. The probability that both score is 1 minus each failure probability combined: (1 - 0.202) x (1 - 0.333) = 0.532, so fair odds are about 1.88.

Real matches are not perfectly independent — a red card or an early goal changes both teams’ rates at once — so a small correlation adjustment is applied. Our model shades BTTS Yes slightly down in matches with a heavy favourite, because blowouts produce clean sheets more often than independent Poisson predicts.

Backing BTTS on reputation. "Both attacks are good" is not an edge; the market already prices attack quality. The edge is in defensive variance — sides that concede in almost every match while scoring inconsistently are where the Yes price is often too long.

Ignoring the league baseline. BTTS clears 56% in the Süper Lig and 32% in the Ghana Premier League. Using one mental default across every league is the single most expensive habit in this market.

BTTS is the backbone of the Nigerian coupon and is priced short precisely because it is over-backed locally. Comparing the same BTTS selection across two Nigerian books regularly shows a five-to-ten-point price gap — that spread is often larger than any edge the selection itself carries.
