Losing it: Kaká and other good soccer players turned bad • 01/22/2013, 05:55 PM

The only constant in sports is that it's always changing. Take the good or great players of today. Tomorrow, they might not be that good. In fact, they could be downright awful. Along those lines, Terra presents an offering of some very good-to-great players who have lost their touch and are now painful to watch... if they even get on the field that is.

Kaká: He was a star at Milan where he played for 6 seasons, became an idol and even won the FIFA Player of the Year and Ballon d'Or in 2007. After transfering to Real Madrid he has not been the same player, being affected by injuries and relegated to a secondary role. At the international level, Kaká was not called for over 2 years to the national team after the 2010 South Africa world cup.

Fernando Torres: 'El Niño' is still an icon at Atletico Madrid where he started in the youth team. He also enjoyed great success in his 4 seasons at Liverpool, but has lost his scoring abilities after moving to Chelsea becoming the highest EPL transfer in history.

Andriy Shevchenko: 'Sheva' was Milan's star striker for 7 seasons. He even won the 2004 Ballon d'Or award. After he moved to Chelsea for a then EPL record transfer, Shevchenko never established as a top striker, staying on the bench most of his two seasons there. He went back to Milan for one season but failed to score any league goals and only 2 in 26 appearances in all competitions.

Djibril Cisse: The French was a scoring machine at Auxerre but after a moved to Liverpool he suffered a freak injury suffering an open fracture of his leg. He moved to Marseille where he broke his leg again. Although he had a succesful stint at Panathinaikos, Cisse was never the same after the injuries.

Ronaldinho: He was the best player in the world while he played for Barcelona where he won the FIFA World Player of the Year twice in a row. After being dimissed by Guardiola, he moved to Milan and it was downhill for him. Indiscipline and lack of commitment are some of the reasons this fantastic player has not been what he used to in Barcelona.

Michael Owen: England's wonder boy, he played the1998 World Cup at just 18 and made an impact in the tournament.He was Liverpool's top scorer every season from 1998 to 2004. After he moved to Real Madrid at 25, Owen lost his scoring prowess. Injuries helped dimish Owen's condition. He currently plays for Stoke City.

Alexander Hleb: He was Belarus' most famous player after he enjoyed great success at Stuttgart and Arsenal, but his move to Barcelona was a failure and he returned on loan to Stuttgart, playing for 4 more teams since and then returning back to his native country to play BATE Borisov.

Denilson: After debuting at 17 with Sao Paulo, the Brazilian became the world's most expensive transfer when he was bought by Real Betis at just 21 years old. Although he spent 6 years there, he never fulfilled expectations and was often on the bench in his latter years, to end up playing in in the Saudi Arabia league and the MLS with little success.

Freddy Adu: Making his professional debut at 14 years old with the DC United, he was thought to be the next Pelé. Since then he's been in 8 teams, failing to become a regular starter in the last 7 teams he's played for. He recently left Philadephia Union and will play in a ninth team at age 23.

Johnier Montaño: He was a highly rated Colombian player who was playing at age 15 in Argentina's Quilmes and was acquired by Italian Parma at 16, debuting with the Colombian national team at the same age. Set to become a star, indiscipline problems affected him and went to a nomadic career through several lower level clubs. His last game with the national team came a 20 years old and never was called back.

Jonathan Woodgate: The English defender was regarded as one of the best players to come out of the Leeds United academy. After succesful stints with Leeds and Newcastle, he was acquired by Real Madrid at age 24 but his career was affected by several injuries and never regained the level showed at the begninning of his career.

Jose Antonio Reyes: Debuting with Sevilla a age 16 and becoming an idol, he moved to Arsenal where he was successful, earning several called for the Spanish national team including the 2006 World Cup. After his loan to Real Madrid, Reyes would not be called up again for Spain and after going to Atletico and Benfica he is now back at Sevilla.

Mario Jardel: The Brazilian was the top scorer of the Portuguese league 5 times (4 in a row), and the top scorer of the 2001-02 UEFA Champions League, but after he moved to EPL's Bolton, he forgot how to score and ended playing for 14 different teams after.

Jari Litmanen: Considered Finland's best soccer player of all time, he enjoyed great sucess at Ajax where he became an idol. While a the Dutch club, he won several titles including the UEFA Champions League and was that tournament's top scorer the following season. His level fell dramatically after he was signed by Barcelona at age 28 to follow his coach at Ajax Louis van Gaal.

Mateja Kezman: This Serbian became a scoring machine at Patizan and then Dutch PSV, but after he was acquired by Chelsea at age 25, he lost his scoring skills and has played for 8 different clubs with no success.
