Michu's move to Napoli from Swansea City appears to have been completed after the Italian's club's president Aurelio De Laurentiis welcomed the Spaniard's arrival on Twitter.
De Laurentiis confirmed this week that the club have been in talks with Swansea regarding the capture of Michu.
While no details have been announced just yet, widespread reports have claimed that the forward will join Rafael Benitez's side on a season-long loan.
The 28-year-old signed Swansea in 2012.
