The England and Wales Cricket Board has refused to comment on reports of a rift between national team captain Kevin Pietersen and coach Peter Moores.
It has been claimed the pair clashed over the decision not to recall former skipper Michael Vaughan for the forthcoming tour of the West Indies.
Pietersen is thought to have wanted Vaughan alongside him in the Caribbean but selectors opted to keep faith with Ian Bell and Owais Shah.
An ECB spokesman said: "We don't comment on speculation."
It was also claimed Pietersen had demanded showdown talks with ECB officials over the matter, but no such meeting is due to take place.
Recalling Vaughan would have proved a controversial move given the Yorkshire batsman's poor form towards the end of last season.
Vaughan returned to his county after resigning as England captain last August but did not do enough to earn a place on the tour of India and ended the season injured.
He remains centrally contracted but has not played any competitive cricket since the end of the season and has no form to back up his case for a return.
