Victory at Augusta National this month, live on Sky Sports, would see McIlroy emulate Woods, Jack Nicklaus, Gene Sarazen, Gary Player and Ben Hogan as the only men to claim all four major championships.

The Northern Irishman will tee it up at the Valero Texas Open this week before heading to Georgia for The Masters, a major at which he has recorded seven top-10 finishes but missed the cut twice in the past three years.

Speaking on the 'I Can Fly' podcast, McIlroy said: "I went last week to see Butch Harmon for a golf lesson.

"I've seen him over the years, like once every few years. I'll say, 'Hey, Butch, can I just come see you and you can take a look and see what you think'."

Speaking further about Harmon during his press conference ahead of the Valero Texas Open, McIlroy said the trip was "worthwhile", adding: "I met Butch when I was 14 years old, so we've always had a good relationship. If there's one guy that I want to go and get a second opinion from, it's him.

"After The Players, struggling through that Florida Swing with my swing and with some of the misses I was having with my irons, I just thought to myself 'I'm obviously missing something here' and that I would love to get him take a look, get a second opinion, a second set of eyes.

"The one thing with Butch is when you go and spend time with him, you're always going to feel better about yourself at the end of it whether you're hitting it better or not. He's sort of half golf coach, half psychologist in a way.

"I went and spent probably four hours with him in Vegas. He said a couple of things to me that resonated.

"It's the same stuff that I've been trying to do with my coach Michael [Bannon], but he sort of just said it in a different way that maybe hit home with me a little bit more.

"It was a really worthwhile trip and I feel like I've done some good work after that."

McIlroy: I feel I've made some big strides

On where he feels he is with his golf, McIlroy added: "I think my game's shown signs of life in all different departments over the course of the year. Some week's the driving's good, some weeks the irons are good. It's just trying to put it all together.

"I feel like I've made some pretty big strides, especially with some of the things I was struggling with. That's why this week is a great week to tee it up and see sort of where the last couple weeks of work has gotten me.

"The results haven't been what I would have liked, but I've learnt a lot about where my game is.

"If I hadn't played as much over the past couple of months, I maybe wouldn't have started going down this path that I'm on of trying to clean up the technique a little bit.

"I think it's been good. There's been struggles in there too which aren't great, but I think looking at the bigger picture, if I can get through that and get my game to a really good spot where I can play great now from April through to August, I'll be happy."
