Rory McIlroy's former manager has claimed that the Northern Irishman will win at least 10 major tournaments in his career.
McIlroy left Andrew Chandler's agency, International Sports Management, soon after his first major win in the US Open despite being with the company since he was 17.
However, Chandler does not hold a grudge over the decision and believes that McIlroy can become one of the greatest players in history.
The former player told the Daily Mail: "We had four-and-a-half years of helping to nurture an unbelievable talent.
"And, with our without ISM, Rory will become a great player.
"He will go on to win 10 majors, maybe more."
The 22-year-old is expected to be a major contender for the Masters, which starts at Augusta on Thursday.
