Swansea have announced that Michu has joined Napoli on a season-long loan deal with the Italian club holding an option to make the transfer permanent.

The 28-year-old, who arrived at the Liberty Stadium in July 2012 from Rayo Vallecano, completed a medical with Rafael Benítez’s side on Thursday morning.

Michu scored 22 goals in all competitions during his first season at Swansea but struggled to recapture that impressive form last term as injuries took their toll. It is understood Swansea were keen to agree a permanent transfer for Michu, who managed only two goals in 15 Premier League starts in 2013-14.

The Napoli president Aurelio De Laurentiis tweeted a message of welcome to Michu on Thursday afternoon. De Laurentiis wrote: “Benvenuto a Michu”.
