"The legal dispute between Rory McIlroy and Horizon Sports Management has been settled to the satisfaction of both parties, who wish each other well for the future," it said.

"To be named the European Tour's Golfer of the Year for a second time is a huge honour and one I am extremely proud of," he said.

"This award is a very nice way to round off the year. The European Tour has always been good to me, so it is always special to be recognised in this way. Hopefully I can have more years like this one and win the award again."

World number one Rory McIlroy has been voted PGA Tour player of the year for the second time in three seasons.
McIlroy won the Open Championship, WGC-Bridgestone Invitational and US PGA Championship in consecutive appearances and did not finish outside the top 25 in any of his 17 PGA Tour events in 2014.
The 25-year-old had already claimed the Arnold Palmer Award as the tour's leading official money winner (£5.1million) and won the Byron Nelson Award for adjusted scoring average (68.83).
"It means a lot to win it for the second time in three years," McIlroy said. "Being voted player of the year by your peers is something that's very important.
"They are the guys you are trying to beat week in, week out and if they appreciate what you have done over the year, see the hard work that you've put in and the golf that you've played and think that's been the best of the season that means a lot to me.
"I would like to win a lot more in my career and even though the last year wasn't what I wanted, the last three or four years have been very, very good and it gives me even more motivation to go on and work harder and try to win more tournaments, more majors and be involved in more Ryder Cups like last week."

Rory McIlroy's last competitive outing saw him battling for a £7million payday in the Tour Championship, but the world number one is equally fired up by the thought of playing for team glory at the Ryder Cup.
The 25-year-old famously labelled the Ryder Cup as an "exhibition" the year before his debut in 2010, but contributing to narrow victories at Celtic Manor and Medinah means he appreciates the special nature of the biennial contest.
"It's a group of people that you know well and they all have one goal, one collective task which is to win the Ryder Cup and beat the US team," McIlroy told BBC Radio Five Live.
"The money doesn't matter to us any more, it doesn't matter if we're playing for millions of pounds all over the world. This means as much to us or even more than any other thing that we play for. It's a big deal to us, we want to play as well as we can and try to win."
