Mika Väyrynen (born 28 December 1981) is a Swedish-born Finnish former footballer. Club career Early career Väyrynen started his career with FC Lahti and joined FC Jokerit for the 2001 season. Heerenveen Midway through that year SC Heerenveen beat Internazionale to his signature, Väyrynen opting for the Dutch club in order to have a better chance of a regular starting place. He immediately broke into the Heerenveen side, though the switch from a summer to winter season meant he began to suffer from injury problems. However, in 2003–04 he became their key player in midfield, and ended up scoring 17 goals in 100 Eredivisie games. PSV In the summer of 2005, Väyrynen joined PSV, upon joining stating, "PSV is the best option for me. At Heerenveen I learned to play more simple football. I am not the player I was in Finland any more, tactically and physically especially I have grown a lot." He was brought in to replace Mark van Bommel by PSV manager Guus Hiddink. Väyrynen was, however, ruled out for much of the early 2005–06 season with an ankle injury. Väyrynen returned to action as a substitute on 17 December 2005 against Willem II, and immediately scored his first goal for PSV. He was not able to earn a regular starting place in the spring season, and mostly made substitute appearances, as PSV secured the Dutch title for the second year in a row. Väyrynen was linked with a move to Rangers and newly promoted Premier League side Derby County as they looked to strengthen for the 2007–08 season. Väyrynen almost moved to Derby in August 2007, but the move collapsed because of a calf injury. In the summer of 2008, Väyrynen was again linked with Rangers and an undisclosed Belgian team, believed to be Club Brugge. He was also linked with Derby for the second time on 22 July 2008, according to Derby's local radio, despite their relegation to the Championship. Heerenveen 31 August 2008, two days before the closing of the transfer window, Väyrynen was signed by former club Heerenveen to a contract until 2011 with an option of one year more. He picked up a knee injury in a January 2009 match against Ajax which ruled him out of play until the end of 2009.
