There could be a club v country row brewing, involving Cameroon, Liverpool's Joel Matip and Allan Nyom of West Brom.

Both players have been named in Cameroon's 35-man provisional squad for the Africa Cup of Nations.

Matip and Nyom are two of seven squad members who have said they do not want to go to the tournament, but Cameroon team manager Alphonse Tchapmi says he expects them both to arrive at their training camp in the city of Yaounde tonight.

"We have three players who are due to arrive (Tuesday evening), notably Allan Nyom and Joel Matip. The third player is Eric Maxim Choupo Moting," he said.

Cameroon's coach Hugo Broos said last month that "the federation reserves the right to take action against the players in accordance with Fifa regulations."
