The two former team-mates traded words over the Portugal star's placement on the touchline during a Champions League tie at Young Boys
Manchester United manager Ole Gunnar Solskjaer brushed off speculation that Cristiano Ronaldo was running the team from the sidelines during Tuesday's defeat to Young Boys, saying that Rio Ferdinand was not aware of the real situation at the club when he made those comments.
Ronaldo's goal at Young Boys wasn't enough in United's Champions League opener, as the 10-man Reds went down to a surprise defeat in Switzerland.
The striker was pulled off during the second half but retained a vocal presence on the touchline, to Ferdinand's concern.
