The Real Madrid superstar has just become the highest-paid footballer in history with a five-year deal which earns him £285,000 a week After tax.
Now, he is expected to agree a new boot deal with Nike in the next few months.
His current agreement with the American sportswear company, worth £5m a year, expires in 2014.
Industry sources believe it will be replaced with a new deal worth £8m a year over five years.
Ronaldo, 28, then looks like being a global ambassador for Nike, just like tennis legend John McEnroe and basketball icon Michael Jordan, meaning he will rake even more money in.
At this rate, the former Manchester United hero will be changing his name to Ronaldough!
United, meanwhile, pay out almost £5m in compensation to Sir Alex Ferguson’s staff when the manager retired in May.
Fergie’s successor, David Moyes, brought in his own backroom staff, including Phil Neville from Everton and his old Goodison No.2 Steve Round.
That meant the Old Trafford club had to reach a financial settlement with assistant-boss Mike Phelan, coach René Meulensteen and goalkeeping coach Eric Steele.
The club admitted that it had to make “compensation payments to former coaching staff for loss of office” in the exceptional items section of their accounts, released last week.
