Ronaldo scored his 15th goal of the season against Spurs on Saturday, a goal that will earn him £400 from Ferguson, from a bet they agreed on before the season.
Ronaldo said on gestifute.com: “When I return to Manchester I will talk to him.
He added: “It’s good to be in this position. But the most important thing is that we won and that we have a six-point advantage over Chelsea.”
