But Ronaldo only met with club doctors, as well as medical staff from the Portuguese Football Association, to assess the midfielder's ankle injury.

Wednesday's meeting between Ronaldo and United doctors took place in Lisbon.

No decision has been made on whether the 23-year-old will have surgery on his right ankle.

"Manchester United medical staff met with the medical teams of the Portuguese FA and Cristiano Ronaldo in Lisbon on Wednesday regarding the ongoing treatment of an injury to his right ankle," United said in a statement.

"As a result, further specialist advice is being sought and an announcement will be made on any action in due course."
