Cristiano Ronaldo latest transfer news and rumours: Showdown talks to begin with Man United as Alex Ferguson visits Carrington

Cristiano Ronaldo rocked Manchester United's preparations for their new era

under Erik ten Hag by requesting to leave Old Trafford.

Ronaldo, 37, did not return to training as planned at the start of July on account of "family reasons"

and was not part of the travelling party for United's preseason tour of Australia and Thailand.

The five-time Ballon d'Or winner is reportedly keen to keep playing Champions League football

something that is not in United's immediate future after they limped to sixth place in the Premier League last season

United's public stance is that Ronaldo is not for sale and under contract until 2023

although it is hard to see this potential saga playing out in such an uneventful fashion.
