Golfing great Sir Nick Faldo has explained the phenomenal swing action of four-time major winner Rory McIlroy, while also discussing aim-point express.
The 2014 Open champion McIlroy is among the favourites to claim his fifth major title and, after missing out last year, the Northern Irishman will be determined to add to his impressive trophy haul.
Former world No 1 Faldo was in the Sky Sports Open Zone to analyse his swing, explaining the importance of his wrist and left knee movement.
McIlroy's turn, tempo and legendary follow-through all caught Faldo's eye as he offered a unique insight into the 27-year-old's action.
Watch the video at the top of the page to see Faldo talk to Nick Dougherty about McIlroy at Royal Troon, venue for The 145th Open, live on Sky Sports.
Faldo also discussed aim-point express - the new phenomenon in the world of golf in reading a putt.
The trick, according to six-time major champion Faldo, is the distance from your finger to your eye, lining it up from right to left and getting a distance from the right of the hole.
It is all about calculation and learning to feel the greens, but also attempting to do the same thing every time on very putt.
