Rory McIlroy is hoping to end a four-year wait for a major title at Carnoustie this week but the 29-year-old is not overly concerned by the length of the drought.

Speaking to media on the eve of the tournament, McIlroy said: "I have had a decent career up to this point and I have a lot of time to add to the major tally.

"It is hard to win any week on tour, let alone the four big ones. I was on a nice run from 2011-14. I have not won one since but I am trying my best." 

McIlroy impressed as an 18-year-old at the last Open to be held at Carnoustie in 2007, winning the Silver Medal as the leading amateur. He admits could benefit from trying to approach this tournament in a similar care-free manner.

The 29-year-old said: "Sometimes the pressure that it is put on the top guys to perform starts to wear you down. When I look back at those pictures, the more I can be like that the better." 

McIlroy, who won at Hoylake in 2014, feels he has been close enough to mount a challenge in recent Opens but has fallen short on the final day.

He said: "If you put yourself in position hopefully you can get it done. Hopefully I can find a way plenty more times before I finish."
