Liverpool have withdrawn Joel Matip from the squad for their match against Manchester United at Old Trafford after FIFA failed to provide the necessary guarantees he was available for selection.
The 25-year-old Cameroon centre-back retired from international football in September 2015 but national team coach Hugo Broos subsequently tried to call him up for the African Nations Cup.
Matip made his position clear to Broos and his club, and in the lead-up to the tournament Liverpool were relaxed about the situation despite Cameroon officials still making noises about him being selected.
