4 Potential Opponents for John Cena at SummerSlam

The franchise. — John Cena has delivered some great matches at SummerSlam

#1 The Undertaker

Who else? The most anti-climactic WrestleMania match of all time needs more to it. Undertaker's squash of Cena at WrestleMania 34 made very little sense to most people.

No one knew what was the endgame, but now it seems clearer. Cena and 'Taker could meet on the second biggest show of the year and add another chapter to this seemingly bizarre rivalry.

This may be the least exciting and most uninspired choice, but is the only one that makes sense in the WWE scheme of things.

Cena and Undertaker have to follow up on their WrestleMania match, and this is a perfect second chapter. Cena could probably challenge 'Taker again at SummerSlam or somehow manage to get 'Taker to face him using unconventional means.

This could set up a main event worthy match, which wouldn't necessarily be great from an in-ring perspective, but could be a tremendous psychological affair.

The winner has to be Cena if WWE wants to add a final grudge match to finally send 'Taker into retirement at WrestleMania 35.

This may be the biggest match on the list, however, it may not be the most exciting.
