John Marquis, Ellis Harrison and George Hirst haven’t shared the load efficiently this term and have left a lot to be desired in their individual performances.
As a result, Danny Cowley will be forced to bring a new face to Fratton Park in two months time in a bid to end their misfortune in front of goal.
And there are a number of highly experienced forwards who could fit the bill and fire the Blues up the League One table.
On the other hand, the club may also look to the loan market once again if they decide to free up one of their, already filled, spots.
Click through the list to see who is a viable striking option for Pompey in January.
