The three players admit it was a difficult few weeks at City as they attempted to impress manager Sven Goran Eriksson.

''Apart from obtaining a work permit, another problem for us is language,'' Teerasil told the Bangkok Post. ''We are not very good in English and sometimes we did not understand what Sven wanted us to do.''

Fullback Suree Sukha is wanted by City and an appeal against a work permit rejection will be heard next month.
