Wales’ assistant coach Raymond Verheijen quit on Friday, accusing the Football Association of Wales of “political and destructive games”.

“Earlier today I have informed the FAW I will resign. Have enough of their political & destructive games. Very sad day,” he wrote on Twitter.

“Very proud to be part of FIFA’s most improved team in 2011. Would like to thank the players and fans for an amazing journey.”

Dutchman Verheijen was brought into the Welsh set-up by former manager Gary Speed, but following Speed’s death in November, his position had been uncertain.

New manager Chris Coleman has held talks with Verheijen and Osian Roberts, who also worked under Speed, and the pair were due to take control of the side to face Costa Rica in a memorial match for their former boss next week.
