5 superstars who could answer Reigns' open challenge

#2 Seth Rollins

No bad blood between the brothers.

Yes, the Shield has reunited, but that doesn't mean we can't see the brothers-in-arms facing each other! Seth Rollins has won every title in the company apart from the Intercontinental Championship and him answering Roman's challenge, just because he wants to complete his Grand Slam will be a tremendous sight.

Seth was the first superstar to win a title after the Shield broke up but currently, both Reigns and Ambrose have completed their Grand Slam but not Seth. The Architect could answer the challenge in a friendly way and produce an instant classic.

No matter what the result is, the fans will be in for a treat to see the Shield mates fighting each other. However, WWE needs to keep this a strict one-off match and not sow the seeds of a Shield breakup, if this match ever happens.
