Jiangsu coach bales transfer was 90 percent done but madrid changed their mind

It seems like you're referring to a recent transfer news involving Jiangsu FC and Real Madrid.

From what I understand, Jiangsu FC's coach, Olaroiu, had reportedly agreed to a transfer deal with Real Madrid, with the transfer being 90% done. However, it appears that Real Madrid changed their mind and decided not to pursue the transfer.

Can you tell me more about what happened? Was there any specific reason why Real Madrid decided to back out of the deal?
