2 Superstars The Undertaker should face at SummerSlam and 2 Superstars he shouldn't 

The Undertaker made a shocking return on RAW last week when he saved Roman Reigns from Shane McMahon and Drew McIntyre. The Phenom will now team up with Roman Reigns to take on the team of Shane and Drew at Extreme Rules.

The Undertaker's last fight was at Super ShowDown where he locked horns with Goldberg in a dream match, however, the match didn't live up to the hype. Subsequently, the Deadman came to rescue Roman Reigns as the latter was put in a Handicap Match on RAW.

Since Undertaker will be part of Extreme Rules, he is likely to compete at SummerSlam, which is just one month away. SummerSlam is one of WWE's biggest pay-per-views and Undertaker's inclusion could be a major boost. It will be interesting to see who will face the Phenom at SummerSlam. Some Superstars deserve to face the Deadman, while some Superstars are not suitable to have a match with The Undertaker.

Here we discuss two Superstars who should face the Undertaker at SummerSlam and two Superstars who shouldn't:

#2 Should face: Drew McIntyre

Will we see it?

Drew McIntyre, who will cross paths with the Phenom in a Tag Team match at Extreme Rules, could be a great opponent at SummerSlam. Considering the Undertaker is part of the storyline, the two men have a bright possibility to face each other at SummerSlam. McIntyre and Undertaker never fought each other and it should be an exciting battle.

There is no denying that McIntyre is currently one of the biggest heels in Vince McMahon's company. The Scottish Psychopath made his main roster return last year after a successful stint in NXT. He won the NXT Title on the developmental brand and has established himself as a top Superstar on RAW.

Due to the age of the Undertaker, he might not match the agility of McIntyre in the squared ring, nevertheless, they are competent in delivering a decent match at SummerSlam. Regardless of the outcome of the bout, a match against the Deadman will elevate the stature of McIntyre.

#2 Shouldn't face: Shane McMahon

Since Shane McMahon will team up with Drew McIntyre, the former will cross paths with the Undertaker at Extreme Rules. Though Undertaker and Shane are part of the storyline, it will not be a wise decision to book a match between the two men at SummerSlam. Furthermore, the two men already locked horns in the past and there is no point in having another match.

Shane and Undertaker faced each other at WrestleMania 32 where they delivered a solid match. It was a Hell in a Cell match but Shane's jump from the top of the cage was the most memorable moment of the match. The Phenom won the bout after pinning Shane.

Both men are in the twilight of their careers. Moreover, Shane is not a big draw and he should not get a push to face the Deadman. The fans have been vocal about Shane's recent push and he is certainly not a deserving candidate to headline SummerSlam against the Undertaker.

#1 Should face: Roman Reigns

A rematch?

There is no denying that Roman Reigns could be an ideal choice to face Undertaker at the biggest show of the summer. Even though Undertaker and Roman Reigns will be in the same team at Extreme Rules, we could see a twist. A heel turn for the Phenom could lead to a blockbuster match between Reigns and Undertaker.

When Undertaker showed up to rescue Reigns last week, it didn't make sense. The two men have a history as they faced each other at WrestleMania 33. Apart from Brock Lesnar, Reigns became the only other man to defeat The Undertaker at the Grandest Stage of Them All. A large number of fans assumed that it was the last match for the Phenom as he left the wrestling attires in the ring. However, the Undertaker came back and he is still wrestling.

The rivalry could restart after Extreme Rules and the Phenom could take revenge for his previous loss. Judging by the hype of their last bout at Showcase of Immortals, they could tear the house down at SummerSlam.

#1 Shouldn't face: Goldberg

Undertaker and Goldberg

Goldberg and Undertaker fought each other at Super ShowDown where the latter pinned the former. Since they were facing each other for the first time in their careers, the anticipation was sky-high. It was a dream match between two legendary Superstars. Unfortunately, the dream match turned into a disaster in Saudi Arabia.

Due to the age of Goldberg and Undertaker, the match was slow, moreover, the match was filled with some shocking botches. The former Universal Champion was busted open at the beginning of the match. While Goldberg failed to deliver a proper Jackhammer, the Undertaker also botched the Tombstone Piledriver. The match had an unusual finish as Goldberg got pinned after a Chokeslam from the Phenom.

The two legendary Superstars certainly garner the attention of WWE Universe but a rematch will not be a smart move. Either of the two Superstars could have been seriously injured in their last bout at Super ShowDown, hence, another match between the two aging Superstars could be disastrous at SummerSlam.
