West Brom have angrily rejected claims from Fifa president Sepp Blatter that the club field weakened teams against the top Premiership sides.
Blatter alleged an Albion official told him they do not play their best line-up against the top sides because "they know they are going to lose".
However a club spokesman said: "We are astonished and totally mystified by Mr Blatter's remarks.
"We utterly refute what Mr Blatter suggests," he added.
The comments referred to the defeat West Brom suffered at the hands of champions Chelsea in August.
Albion lost 4-0, having made five changes to the team that had beaten Portsmouth four days earlier.
And the club have always rejected claims that they were attempting to rest players for the contest with Birmingham later that week.
"We can categorically state that no Albion official has spoken to Mr Blatter this year - let alone in the past month," added the West Brom spokesman.
"The management of the club field what they consider to be their strongest available side for every game - and will continue to do so.
"As always, this will be the case when the team plays against Arsenal on Saturday.
"It is also worth pointing out to Mr Blatter that we did in fact draw our away games at Arsenal and Manchester United last season."
