Even Cena haters have to give it to the guy, he's had some fantastic performances in 2015. As for The Undertaker, he's right back on form, having just delivered a really good match with Brock Lesnar at Hell In A Cell. Both men have a history of excelling in big match performances. They are very good pro wrestlers, with a ton of experience. If WWE put them together in a match, the chances are they'll deliver something of exceptional quality. Even more so when backed by such a large and passionate crowd. Indeed, you'd expect nothing less than a match of the year contender from these two at WrestleMania. WWE know that and will be keen to book it for that reason.
