GMS contributor Nevo Nahmias looks at five players who promised so much, yet delivered so little.
5. Shaun Wright-Phillips
The Englishman came through the ranks at Manchester City and was very good in his early days for the Citizens. At times he looked like he could be a real star on the international stage.
A dream move to Chelsea came in 2005 but Wright-Phillips didn't progress in Jose Mourinho's side and had to move back to Manchester after he scored no more than four goals in his three year career at Chelsea. He later became a QPR and is now plying his trade in the Championship.
4. Ricardo Quaresma
Starting his career at Sporting Lisbon, Quaresma was supposed to be one of the greatest wingers in the world. He made a quick switch to play for Barcelona where he didn't progress as imagined with the Catalan club.
He then had a great four year spell at Porto, which earned him another chance on the big stage as he moved to Inter Milan.
In Italy, the Portuguese winger made just 24 appearances scoring only one goal and was also sent on loan to Chelsea where he made only four appearances.
He soon moved to Besiktas and, after two years at Turkey, he moved again to Al Ahli Dubay. Quaresma is currently a free agent.
3. Yohan Gourcuff
The French playmaker is currently trying to help Lyon relive their glory days in the French league. He started his senior career at Rennes before sealing a big money move to AC Milan. After failing to impress and was loaned to Bordeaux where he impressed, scoring 12 goals there.
There is still time for they young man to reach his potential, but he will need to move to a bigger club than the French outfit.
2. Michael Owen
Although he played for teams like Liverpool, Manchester United and Real Madrid, everybody expected more from the Englishman, especially in the national team.
Owen made his senior debut at Liverpool and after a successful period with the Reds, he moved to Real Madrid in an attempt to get some Champions League glory. But after an injury-hit season he came back to the Premier League to play for Newcastle, Manchester Untied and Stoke City before retiring.
1. Obafemi Martins
The super quick Nigerian striker made his breaktrhough at Inter Milan but in his five years at the club he was able to made just 88 appearances after injuries came back relentlessly.
He played for Newcatle, Levante, Wolfsburg and Rubin Kazan but didn't fulfil his potential. He is now playing for MLS side Seattle Sounders at the age of 28.
