Wales lose Euro 2004 appeal

"It's disappointing and frustrating because cheats have prospered," said Hughes after the Court of Arbitration for Sport ruled against Wales.

"We had a good case, but the verdict devalues the European Championship."

Wales wanted Russia thrown out of the Portugal tournament after their player Egor Titov failed a drugs test after the first-leg play-off last year.

The CAS in Lausanne backed two decisions from Uefa in ruling that Wales had failed to prove that Russia were implicated in Titov's drug taking.

Hughes told BBC Wales that his side were determined to move on from the decision as they target the autumn's World Cup qualifying campaign.

"It has been a long fight (against Russia), but at this point we have to draw a line under it," said Hughes.

"We have two friendlies at the end of the month which we will use to prepare for the World Cup qualifiers.

"I will then go to Portugal to watch our qualifying opponents England. It's time to concentrate on the football."

The Wales boss did hope that the protracted legal battle would change the way football's governing bodies deal with drugs issues.

"I think the arguments we presented will make a difference," said Hughes.

"Uefa will probably change their regulations or procedures and we should be congratulated for that."
