The duo have been paired at the Abu Dhabi HSBC Golf Championship, and Fowler says he is looking forward to playing against the Northern Irishman once again.
Fowler said: "Obviously Rory and I got to play a bit last year, a couple final groups, and we'll see if we can make it a little bit more fun this week.
"Rory is the best player in the world right now and proved that last year.
"I'm definitely looking forward to 2015, having some great match-ups with him, along with some of the other great young players.
"It's not just 2015 to look forward to but the rest of our careers.
"We have a lot of time that we're going to be able to play against each other and this is really just the start of it.
"I'm really looking forward to it, and I feel like we're going to have some fun and heated battles at times.
