Seems like he's negotiating with Morocco NT to stay in Barcelona instead of going to the Tournament.
That would be the smartest move all things considered. Going to the ANC could realize jeopadize this once in a lifetime opportunity of establishing him as a Barcelona first team option. Especially if new signings come and he finds himself down the pecking order come February.
The other point is that the next Cup of Nations is in 2023 where it will be moved to Summer. So more suitable for all parties.
