Nigeria-born Former Polish striker Emmanuel Olisadebe has revealed that moving from big club, Panathinaikos to very small club, Portsmouth in England was the biggest regret of his football career.

Olisadebe was a leading player of the Polish national team in the qualifying round for the 2002 Korea/Japan World Cup.

In an interview published by Polish news outlet, Sport24.gr, Olisadebe remembers the move from Panathinaikos to Portsmouth was his worst.

“I was told I could leave, so I did. I signed a contract with Portsmouth for less money than I had in Panathinaikos.

“It was a very bad decision to leave a club like Panathinaikos for as small as Portsmouth, “he said.

“They did not even have their own training centre.

Changing rooms were in terrible condition. I was in despair when I was in Portsmouth. A hideous city.

With only one shopping centre, no nightlife. The biggest mistake in my career – he added firmly.

After finishing his career, Olisadebe returned to Nigeria.

“I live permanently in Nigeria. For some time in Lagos, earlier in the eastern part of the country.
