Lomana LuaLua has threatened to quit Fratton Park after talks over a new deal broke down.
The 25-year-old striker was Pompey's joint leading scorer last season with seven goals as the south coast club avoided relegation.
Now, however, the Democratic Republic of Congo international has admitted he may move as he enters the final year of his contract.
LuaLua told the Daily Express: 'It looks as if a move could be an option.
'Maybe they want to cash in knowing I could leave for free next year.
'It is sad because I love the club and the fans but I have to think of my future.'
