Alexander "The Mauler" Gustafsson has been waiting over five years to get another crack at Jon "Bones" Jones. The Swede will finally get his opportunity for the rematch, as the men collide on Dec. 29 in the main event of UFC 232.

Tickets for the show, which goes down at Las Vegas' T-Mobile Arena, are on sale right here on AXS.com. In honor of the fight, here's a look back at Gustafsson's top five moments inside the world-famous Octagon:

5.  A Memorable debut at UFC 105.

All the way back in 2009, "The Mauler" made his UFC debut with a fight against Jared Hamman. He made a statement that night, proving with a thunderous knockout finish that he was on his way to the top of the light heavyweight division. Gustafsson won by KO at the 41-second mark of the very first round.

4. Going the distance with Jones.

Despite walking away with an "L" on his resume, Gustafsson quieted critics with a classic performance against the champ in the main event of UFC 165. It was a back-and-forth, five-round war that left fans itching for a rematch. UFC supporters will finally get their wish on Dec. 29, as the hotly-anticipated rematch goes down in Las Vegas.

3. Scoring a win over "Shogun" Rua.

In December of 2012, "The Mauler" picked up a victory over one of the most legendary names of all-time in the sport of MMA. Gustafsson beat "Shogun" via decision. That night, "Gus" showed off extremely technical striking and high-level takedown defense.

2. Knocking out Glover Teixeira.

In his most recent effort, Gustafsson proved he's still at the top of his game at the tender age of 31. This is a guy with plenty of gas left in the tank. He knocked out Teixeira -- a former world title challenger -- in the fifth round of action.

1. Finishing Jimi Manuwa in 2014.

On a UFC Fight Night card in London in 2014, "Gus" delivered a performance that earned him the nod for "Fight of the Night" as well as "Performance of the Night." He won via TKO in the second frame. Manuwa is a nightmare to deal with, but Gustafsson had no problem picking up the victory. Beating Manuwa solidified his spot as the next top contender to challenge for the light heavyweight title.
