Croatian FA president Vlatko Markovic says West Ham United will face 'mission impossible' if they try to appoint Slaven Bilic following Alan Curbishley's resignation earlier this week.

Bilic has already insisted that he is committed to leading Croatia to the 2010 World Cup after reports on Thursday suggested West Ham want to appoint him after next week's qualifier with England.

"It will be mission impossible," said Markovic told the Daily Express.

"Bilic can't go because there will be a big political problem with Croatia. This is the usual speculation.
