This week ushers in the final episode of Monday Night RAW for 2015 as two big returns invade the Barclays Center in Brooklyn.

Best WWE Matches Of 2015

The WWE is looking to close out the year with a bang and there are several compelling storylines to look forward to on the flagship show this week. There is another live event occurring in Pennsylvania on Monday, so names like Kane, Dolph Ziggler, The Wyatt Family, Team Extreme, Tyler Breeze, Paige and Charlotte may be absent.

Nevertheless, the WWE is stacking the deck this week with the Royal Rumble looming on Jan. 24. Here are five key storylines to watch for on tonight's show.

2015 Year-End Awards For WWE

1) The Boss Is Back

Vince McMahon returned to television for the first time in years two weeks ago, and subsequently was taken out by a Roman Reigns Superman Punch. This week, the chairman returns and will likely be looking for revenge. The WWE is booking Reigns into a "Stone Cold" Steve Austin-esque rivalry with McMahon and the reigning WWE World Heavyweight Champion took to Twitter to comment on the boss' return. Reigns also has to deal with the League of Nations and Triple H.

2) Face Of The Franchise

McMahon isn't the only big return booked for Barclays Center as John Cena is set to make his comeback after returning to action over the weekend. The "Cenation" leader is expected to do battle with Alberto Del Rio, who pinned him cleanly to win the United States Championship at Hell in a Cell, which was the last time the face of the franchise was seen in WWE.

3) Diva Spotlight

With rumors of Paige and Charlotte missing the show, it will be interesting to see how the Divas division is booked this week. Though her boyfriend is returning, Nikki Bella is still expected to miss at least another month with a neck injury, according to F4WOnline.com. With three of the company's top Divas likely missing time, stars like Becky Lynch, Team B.A.D., Brie Bella and Alicia Fox may get a chance to step up.

4) Faction Warfare

Reigns has aligned himself with The Usos and reigning Intercontinental Champion Dean Ambrose, but they have their hands full with the League of Nations stable, which is sure to continue Monday. Sheamus is still gunning for Reigns, while Rusev and Del Rio have been attacking the babyfaces left and right. With Cena now back to go after Del Rio and Ambrose dealing with Kevin Owens, it'll be interesting to see how these storylines mesh.

5) Ready To Rumble

With only four episodes left until the Royal Rumble on Jan. 24 at the Amway Center in Orlando, Fla., the card could start to take shape this week. The WWE has yet to announce any participants in the Rumble Match itself, while the rest of the card hasn't been constructed yet either.

Which return are you most looking forward to this week on 'RAW?'
