The Spaniard is leaving the Liberty Stadium after both the player and club agreed to terminate his deal with the Swans.
The Swans have released the 29-year-old following a difficult injury-hit couple of seasons with the Welsh side, as confirmed via their official website.
Signed from Rayo Vallecano for just £2 million in the summer of 2012, Michu made an instant impact, scoring a brace on his Premier League debut against Queens Park Rangers.
In all, the Spaniard managed 22 goals in 43 games during his debut season at Swansea, helping the club to a memorable League Cup win over Bradford City at Wembley in the process.
Yet injuries and a loss of form curtailed his impact in the 2013-14 campaign, with Michu managing just six goals in 24 outings for the Swans.
Despite this he still earned a call-up to the Spain national team and looked set for even bigger things after moving to Napoli on loan the following year.
Injuries once again took hold, however, with the 29-year-old making just five appearances all season for the Partenopei.
Back at Swansea but seemingly out of the first-team picture, Michu’s departure was confirmed today, with the Spaniard tweeting out a simple but fitting tribute to the club where he made his name, along with a video of some of his best ever goals.
Now likely to head back to Spain in a bid to regain his fitness ahead of a possible move this January, Michu will be fondly remembered by Premier League fans for his goals, smiles and trademark celebration.
