Commission could settle 'leak' row
Cardiff say they have "every faith in the process" after lodging an official complaint with the Premier League over claims their team was leaked to Crystal Palace before a league game between the clubs earlier this month.
It is understood that a n independent commission may be asked to rule on Cardiff's protest.
The BBC have reported that Cardiff argued in their complaint to Premier League chiefs that the 3-0 result on April 5 in Palace's favour should not be allowed to stand.
A Cardiff spokesman said on Thursday night: " A formal complaint has been submitted, concerning what we consider to be a serious breach of Premier League rules
"We have asked for an investigation into the matter, which is now in the hands of Premier League officials who will report their findings in due course.
"At this time it would be inappropriate to discuss any specifics while the investigation is ongoing.
"The club has every faith in the process and will welcome the views of the Premier League."
Cardiff will not comment further while the Premier League probe is under way, including at Friday morning's pre-match press conference that is set to be fronted by manager Ole Gunnar Solskjaer.
Cardiff, currently 19th in the league and three points from safety with only four games left, host Stoke on Saturday.
Premier League bosses will decide whether the complaint should be taken forward - it is understood there remains uncertainty about whether any regulation would have been breached even if the allegation was proven.
If the complaint is taken forward, it could be dealt with by either the Premier League's board or more likely an independent commission.
Cardiff's letter centres on the circumstances surrounding the alleged leaking of their team.
Palace sporting director Iain Moody worked for Cardiff until earlier this season before taking up a post at Selhurst Park in November.
It has been reported that Cardiff believe Moody might have used his contacts at the Welsh club, or close to Cardiff, to find out which players would start against Palace.
Moody, though, has rejected the allegations as "incredibly, extraordinarily untrue" and Palace have also denied the claims.
According to the BBC, the letter from Cardiff's club lawyers runs to five pages and claims the club have proof that Solskjaer's starting line-up was leaked.
