Up until now, 14,596 opposition fans have come through the gates at Fratton Park on a League One match day during the 2022-23 season.
The travelling Owls supporters will see that figure exceed 16,000 come 3pm on Saturday, but which club has had the luxury of the most backing on their trips to Pompey’s famous old home this term?
We’ve taken a look and seen whether it’s made a difference to the Fratton Park scoreline this season.
