Spanish midfielder Michu became Michael Laudrup’s third signing when he joined from Ray Vallecano for around £2million in July.
Michu, full name Miguel Perez Cuesta, signed a three-year deal at the Liberty after impressing in La Liga by helping Rayo stave off relegation.
An attacking midfielder, Michu began his career with local club Real Oviedo in the lower leagues, before moving to Celta de Vigo B in Segunda División B in 2007.
His contract with Celta expired in June 2011 and he signed a two-year deal with Rayo Vallecano, who were freshly promoted to the top division of La Liga.
Physical, tall, hard-working and strong, he became a fans favourite with his ability to time his arrivals into the box earning him 15 league goals and two in the cup.
He became an instant hit at the Liberty Stadium, scoring twice in the opening day thrashing of Queens Park Rangers.
The Spaniard went on to score 22 goals in all competitions, including crucial strikes against Manchester United, Arsenal, Newcastle and Chelsea as the Swans lifted the Capital One Cup.
His form saw calls for him to be called up to the Spanish national team, before he went on to scoop four awards at the club's end of season awards night.
Unsurprisingly, he won the Top Goalscorer gong, as well as Players' Player of the Year, Away Player of the Year and Supporters Player of the Year.
Signed a new four-year contract in January 2013.
