Liverpool boss Jurgen Klopp believes the stand-off between the club, Cameroon and FIFA over the eligibility of Joel Matip is unfair.

Cameroon, competing at the African Nations Cup, are refusing to sanction his release to play for his club as they consider the player to have rejected their approach to name him in their squad.

"I don't have an update. FIFA mentioned to us Friday would be D-Day," said the German.

"The Matip case is obviously, for us, special and we do not feel it is fair.

"We do what we can but we cannot change it and we cannot turn it in our direction because we want it.

"It is difficult in this position because with the fixtures we have at the moment we don't have a lot of training time and you have to work with the team which could start in the next game. And when you're not sure what to do with Joel he is not that involved.

"I had to put me outside this case a little bit because I need my full concentration about other things.

"It is another experience which you don't need but we have to learn from it.

"But it is not about the African Cup of Nations: I absolutely do not have a problem with the African Cup of Nations, it is the opposite.

"I have respect for all what they are doing there in the most difficult circumstances still.

"It is a great tournament - in the middle of our season makes it not too cool but that is not my decision."
