Manchester United say they have "initiated appropriate steps" following Cristiano Ronaldo's explosive, unsanctioned interview, with sources telling ESPN they are seeking to terminate his deal as well as potentially suing for breach of contract.

United have waited until the full extent of Ronaldo's comments were made public before deciding on their response, and after the final part of the interview with Piers Morgan was aired on Thursday in the UK, the club, according to sources, are seeking to end the 37-year-old's contract, which runs until June. Sources added that United have appointed lawyers to explore the possibility of suing Ronaldo for breach of contract.

In a meeting on Monday, manager Erik ten Hag told club bosses including co-chairman Joel Glazer, chief executive Richard Arnold and football director John Murtough that he does not want Ronaldo back after the World Cup, and the Portugal international will be informed he is not welcome back at United's Carrington training base after the tournament in Qatar.
