Yes — 68% confidence
Both teams enter this fixture without a single clean sheet in the Championship this season. Portsmouth have scored five goals and conceded six in their three matches, finding the net in every fixture. Derby have conceded an average of 2.3 goals per game while scoring three. Furthermore, seven of the last ten head-to-head meetings between these sides have seen both teams find the net, indicating a consistent pattern of chances at both ends.
Portsmouth or Draw — 66% confidence
Portsmouth have already registered a league victory this season and average 1.7 goals scored per game. Derby remain winless through three rounds, having collected just one point and conceding seven goals. While Portsmouth are dealing with multiple injury absences, Derby have lost both of their away competitive games this season against Charlton and Rotherham, making the home side or draw the more probable outcome.
These two calls are about different parts of the match (both teams to score and double chance), so neither one determines the other. The figure shown is the lower of the two — a combo can never be more likely than its weaker leg.
