Jimmy Nielsen (born August 6, 1977 in Aalborg) is a retired Danish professional football goalkeeper. In December 2013, he was named the head coach of USL Pro Soccer League's Oklahoma City Energy FC, a club that will begin play in 2014.
Until June 2007, he played 398 games for Danish team AaB Fodbold. Playing every league match for AaB since 1997, Nielsen won the 1999 Danish Superliga championship with AaB. Nielsen has on occasion featured in the Danish national team setup as an unused substitute. He won the 1998 and 2004 Danish Goalkeeper of the Year award.
Nielsen started his career in local amateur club B 52/Aalborg FC. He played youth football for AaB Fodbold, before signing for English club Millwall F.C. in 1994. He did not play for the club and moved back to Denmark, settling in at AaB in 1995. He made his senior debut in 1996, quickly becoming the starting goalkeeper in AaB. Nielsen was one of the cornerstones of AaB, culminating in the 1998–99 Danish Superliga championship.
Nielsen signed a contract with Leicester City on June 4, 2007. He joined via Martin Allen's agent, who claimed he was "another Peter Schmeichel". However, he was left in the reserve squad following the arrival of Hungarian goalkeeper Márton Fülöp. As a result, Nielsen revealed he planned to leave the club during the January transfer window, and was given the green light to do so on November 14. He left the club on January 22, 2008 having his contract terminated by mutual consent without ever having played for the club. The next day he signed a 2½-year contract with Danish team Vejle Boldklub. After the 2009 season, Nielsen was "very close" to retiring after his former club, Vejle Boldklub, was relegated from the Danish Superliga.
Major League Soccer
In February 2010, after having a conversation with and receiving a contract offer from Peter Vermes, Nielsen moved to Major League Soccer team Sporting Kansas City. After his first season, Nielsen stated that he would love to stay with the club another two or three years before considering retirement again.
As reported on December 15, 2010, Nielsen signed a 1-year contract extension to stay with the club through at least the 2011 MLS season. He was sent off for a handball outside the box on June 9, 2011, in Sporting Kansas City's inaugural game at their new stadium, Sporting Park. On November 28, 2011, Nielsen signed a contract extension with Kansas City through the 2013 season. The contract also included an option for the 2014 season. Nielsen received the 2012 MLS Goalkeeper of the Year award. He broke the club record with 0.79 goals against average and helped the team finish first in their division. Nielsen retired following the 2013 season which saw him win MLS Cup.
During a session with the Denmark national under-21 football team in 1999, Nielsen and U-21 teammates Allan Kierstein Jepsen and Peter Degn went to the Munkebjerg casino in Vejle at night to gamble. They were subsequently excluded from all national team practices, a ban that lasted several years. This earned Nielsen the nickname Casino-Jimmy.
Oklahoma City Energy FC announced in December 2013 that Nielsen will be its head coach. OKC Energy FC play in USL Pro, the third tier of the American soccer pyramid. The club is said to be vying for a spot in the top-flight MLS.
