Ronaldo has been asked by those at the Carrington canteen for a list of his preferred foods - which included a traditional Portuguese stew called Bacalhau, consisting of salt cod and eggs, a dish that is thought to have gone down well with his United teammates.
However, a number of other dishes were not so popular.
One United source told The Sun: "He also loves octopus, but most of the lads won't go there - even if it clearly works for Ronny!
"Cristiano is very much into his proteins, stuff like slices of ham, eggs and avocados, and the chefs are trying to help him with a little taste of home."
The diet that Ronaldo follows is so effective the United star holds confidence that he will be able to continue his playing career well into his 40's.
