Huddersfield and Nottingham Forest will compete for a place in the Premier League – whereas teams are preparing for life in the second tier next term.
But which strikers have been let go from the division below the Premier League so far?
Here are the attackers League One clubs – including Pompey – could sign for free this summer.
5. Steven Fletcher - Stoke City
Another well-travelled striker on the list, with Fletcher to depart the Bet365 Stadium after two years. Time is clearly catching up with the veteran as he scored only three goals in 40 appearances last term. Picture: Ian MacNicol/Getty Images Photo: Ian MacNicol
6. Andy Carroll - West Brom
Deemed surplus to requirements at West Brom under Steve Bruce, Carroll is looking for his third club in a year. The Premier League seems past the striker now and League One could be his natural home following injury issues. Scored five goals across his spells at Reading and the Baggies last season.

7. David McGoldrick - Sheffield United
Fresh from play-off heartbreak, McGoldrick will be leaving the club for free this summer. This will end the striker’s three-year association with the Blades after scoring 30 goals. Picture: Jan Kruger/Getty Images Photo: Jan Kruger
