#1 Shouldn't face: 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.
