The Portugal international scored 24 goals in 37 appearances in the 2021-22 campaign after returning to Old Trafford last summer.
However, United's failure to qualify for the Champions League has led to Ronaldo asking the club to be allowed to leave if they receive a suitable offer for him this summer.
Despite Ronaldo expressing a desire to depart the club, Man United are not prepared to sell the 37-year-old.
According to The Sun, the forward is set to hold crisis talks with Ten Hag when he returns to pre-season training next week.
Although United are determined to keep the former Real Madrid player, the report suggests that Bayern Munich and Napoli are showing an interest, while a previous report indicated that Chelsea were leading the race for the striker's signature.
Ronaldo's Man United contract is set to expire next summer. body check tags ::
