The 36-year-old left-hander feels that due to him having won two green jackets in the last three years McIlroy will be the one under pressure to win at Augusta for the first time. The Northern Irishman is chasing a career Grand Slam which adds to it.
"There's no pressure on me – I've got two jackets already. And if you were just looking at me and McIlroy [who had the most pressure on them], I would say McIlroy. If it were the other way around me, then all the pressure would be on me," Watson told media.
"I would actually call it an accomplishment and a huge honour just to have the chance at what, just 25 years of age, to complete the slam. At 25, I was barely able to keep my Tour card. The way he should look at it is that he's got his whole life to try to win the Masters. Yet obviously he's going to put pressure on himself to do it this year.
"I think he would have more pressure than me, because of all the talent he has and the records he could beat when he gets older," he added.
The Masters takes place at the Augusta National Golf Club in Georgia from April 9–12.
