The player looks set to leave the Premier League club after their recent signing of Bafetimbi Gomis, thus threatening Michu’s place in the first-team line-up.
According to The Guardian the move for the 28-year-old is expected to be completed imminently.
The Partenopei are looking to add to their ranks in attack and will be hoping that a move for the former Rayo Vallecano striker will be a low-cost solution to address their depth.
The once-capped Spain international scored 18 league goals for the Swans during his debut season, but injuries hampered his tally the season after, which is looking increasingly likely to have been his last.
A fee is still yet to be agreed by the two clubs and there are further reports which suggest that the former Real Vallecano player’s move could be on a loan basis.
