While trying to call up one of their most important players ahead of two Africa Cup of Nations qualifiers, the Cameroonian Football Federation fired out an email call-up.
Except, according to a report in Bild, they accidentally sent the email to themselves.
So the email never reached Bayern Munich or Choupo-Moting and, subsequently, the player was not officially called up to the Cameroon squad. Apparently all because of an email error.
Frankly, accidentally emailing ourselves is a not unheard of admin mistake. But it's probably best to check the 'send' address twice when you're trying to put together a squad of international footballers.
The 31-year-old Choupo-Moting, who played for Stoke City and Paris Saint-Germain before his 2020 move to Bayern, has 55 caps for Cameroon.
But he won't be adding to that total for the Indomitable Lions in this international break, at least.
The striker's father, Camille, spoke to the media to defend his son from any accusations that he was unwilling to represent his country.
"I was contacted by the association to find out what was going on. I contacted FC Bayern and they confirmed that they had not received the invitation," Choupo-Moting senior told Naja TV per Bavarianfootballworks.
"It looks like she sent it to the wrong email address instead. For me, that's a lack of professionalism.
"When sending invitations, be sure to send them to the correct address. If that doesn't happen, I don't understand why it's the club's or Maxim's fault."
Cameroon face Cape Verde and Rwanda in two AFCON qualification matches at the end of March. But will do so without one of their first-team regulars.
Choupo-Moting instead is staying at home in Munich (presumably continually refreshing his emails to see what shows up).
