**Cash-strapped Portsmouth are understood to have asked the Premier League for permission to sell players outside the transfer window.**However, BBC sports news correspondent Gordon Farquhar said he believes the transfer window is a Fifa regulation.
“I don’t think it’s in the gift of the Premier League to allow Portsmouth to sell players outside of it,” he added.
When approached by BBC Sport, Portsmouth, who are believed to owe about £60m, refused to comment.
