The WWE's European tour continues when "Monday Night RAW" invades the 02 Arena in London England.

With only two episodes of the flagship show until Payback, rivalries are sure to escalate as the May 1 card continues to take shape.

Here are five things to watch for this week on the flagship show:

1) Reigns vs. Styles

After Sami Zayn failed to defeat AJ Styles on "RAW" last week, "The Phenomenal One's" bout with Roman Reigns at Payback for the WWE World Heavyweight Championship remains a singles clash. Bray Wyatt appeared to be set to play a factor in this feud, but he was sent home from the tour with a calf injury, according to F4WOnline.com. There is no word yet on the severity of his injury.

2) Tag Team Turmoil

The tournament to crown new No. 1 contenders for The New Day's Tag Team Championships will continue on Monday. The Usos are set to clash with The Vaudevillians in one semifinal match, while Enzo Amore and Colin Cassady will go head-to-head with The Dudley Boyz. After Karl Anderson and Doc Gallows made their presence felt last week, they're likely to play a role in this week's show as well.

3) Here Comes The Money

Despite the flaws in the storyline basically making his WrestleMania clash with The Undertaker mean nothing, Shane McMahon is likely to run the show again this week in London. The WWE is teasing another appearance by Shane-O Mac, while Triple H and Stephanie McMahon may also resurface after being absent since WrestleMania 32.

"Will we see WWE's Prodigal Son reign once more," the WWE wrote on its website, "or might The Authority put a stop to Shane's tenure as Raw showrunner?"

4) King Of Swing Goes Hollywood

The WWE announced one other match for Payback and it will pit the reigning Intercontinental Champion The Miz against Cesaro. The title-holder's wife Maryse has played a huge factor as of late, and that is sure to continue this week on the flagship show. Cesaro, meanwhile, will likely be booked to gain some serious momentum heading into their title bout.

5) RAW Rivalries

There are a lot of budding midcard feuds in the WWE that are sure to continue as Payback approaches. Dean Ambrose seems destined for a match with Chris Jericho, while the Kevin Owens, Sami Zayn feud will likely escalate into a contest of their own come May 1. Over in the Women's division, Natalya and Charlotte's feud is set to continue, while Becky Lynch has some unfinished business with Emma.
