Former Manchester United striker Terry Gibson doesn't believe Sir Alex Ferguson's retirement will put off Cristiano Ronaldo.

The Real Madrid star is being linked with a return to Old Trafford.

"I think he would go back for (David) Moyes, although it's a bit less certain without Sir Alex Ferguson as manager," Gibson told talkSPORT. "Ronaldo saw him as a father figure, he took a gamble on him when he was very young and he learned so much in his time there.

"But Sir Alex won't be disappearing and I'm sure if United want Ronaldo that Sir Alex will be the person who plays a big part in bringing him back."
