Arsene Wenger's FA Cup winning side will attempt to sell a trio of squad players before offering Porto Â£25million for highly-rated striker Martinez, who has been the subject of interest from a host of top clubs including Arsenal's Premier League rivals Chelsea and Tottenham.
Jackson Martinez, whose agent has confirmed the player could complete a move 'within days', joined Porto from Chiapas in 2012 and has an impressive goal return of 92 goals in 132 games.
The Independent report that Campbell, Podolski and Sanogo could all leave the Emirates with Costa Rica international Campbell being targeted by Spanish sides Villarreal and David Moyes' Real Sociedad.
All three players mentioned spent all of part of last season on loan, with Sanogo appearing for Crystal Palace, Campbell playing for Villarreal and Podolski spending time in Italy with Inter Milan.
German international Podolski still has one year left on his current Arsenal contract and has said he's still open to the possibility of playing for the Gunners again:
"They are a great club and I think I can help them," he said.
"Things can always change, but if needs be I will remain at Arsenal next season."
