Ronaldo scored United’s first goal in the 4-0 win over Tottenham last night.
Fergie made a £400 bet with Ronaldo before the season, that he could not score 15 goals.
Ferguson said: “Maybe penalties shouldn’t count for this bet.
“But it’s a fantastic achievement for Cristiano to score 15 from midfield. The boy has come on great – he always wants the ball.
“It looks like I’ll have to go to the bank now.”
