The legendary former Manchester United manager is understood to have phoned the Portuguese star personally to urge him to return to the Red Devils, 12 years after leaving for Real Madrid.
Talking ahead of Ronaldo’s double against Newcastle, Ferguson told Viaplay: ‘I’m excited like everyone else, there was anticipation all day yesterday and waking up in the morning. I speak for all supporters – it’s a great day for Manchester United.
‘A lot of people played their part (in bringing Ronaldo back) and I contributed knowing that really Cristiano wanted to come here and that was important. It worked very well.
‘I wouldn’t say it’s emotional but it’s exciting for me and relief because I couldn’t imagine him playing for Man City, I don’t think anyone could.
