Sky Sports issued an article reporting the possibility of Zirkzee and Menu leaving the team in January.
Although having players participating in the African Cup of Nations will create opportunities for the two to play, the short-term futures of Zirkzee and Menu will be closely watched as the two players have attracted widespread interest from Premier League clubs, especially on loan.
Zirkzee hopes to get stable appearances to ensure his place in the Dutch national team's World Cup lineup, while Menu also hopes to impress Tuchel if he can get regular game time. He had hoped to leave the team on loan during the summer transfer window.
Amorim has previously admitted that with only one game a week and being in a World Cup year, it has been a challenge to keep all the players satisfied.
If clubs at home and abroad make offers for both players in January, whether on loan or on a more permanent basis, United will need to make a decision.
