Academica striker Ederzito is being tracked by Arsenal.
The People says the powerfully-built ace, who turns 24 on Thursday, is also a target for Porto when his contract expires at the end of the season.
Born in Guinea-Bissau, the 6ft 2in African has told Academica that he plans to move on.
There will be a scramble for his signature and the Gunners have had him watched by chief scout Steve Rowley - but face stiff competition from the Portuguese champions.
