Rayo Vallecano coach Paco Jemez is unhappy with their deal for Dudu.

The Chinese player, Zhang Chengdong 'Dudú', signed for Rayo last week.

"It's been like a slap in the face", the Rayo Vallecano manager told Cadena SER.

"It's not about whether he is good or not, it's the fact that we have been obliged to sign him by a sponsor", he said, making it crystal clear that he was totally against the decision made by his club.

"I'm not at all amused by this new signing. It's possibly the worst decision they have taken since I arrived here."
