During his time as Paris Saint-Germain coach, Thomas Tuchel has found it very difficult to manage two superstar egos in the dressing room.
While Neymar and Kylian Mbappe get on well on and off the pitch, they clash in other areas of football.
They both want to take penalties and freekicks and be the team's top goalscorer, while they're also both obsessed with winning the Ballon d'Or.
That's why PSG are willing to let Neymar go.
A team needs its key players, but it also needs them to put the team first.
"If anyone has to leave, we will sort it out," Tuchel said three weeks ago.
Selling Neymar would allow Mbappe to be the star.
After all, he's the one that wants to take more responsibility - as he said during the Ligue 1 awards.
"We don't want any more celebrity behaviour," PSG president Nasser Al-Khelaifi told France Football.
"Those that don't agree can leave.
"No one forced Neymar to sign [for PSG]."
Al-Khelaifi put across during that interview that Mbappe was untouchable.
He's not on the market, but Neymar is.
The Brazilian's injuries and recent problems off the pitch make him an easier player to sell, but to who?
Real Madrid and Barcelona are the two main candidates.
