Ahead of John Cena's United States Championship match at the Hell In A Cell pay-per-view event back in October, there were several rumours circulating about who is opponent might be.
With names as big as Daniel Bryan in the mix, the WWE Universe had high hopes for someone memorable to step into the ring and overcome the face of the company ahead of his scheduled time-off.
Very few wrestling fans, however, saw what was coming as none other than Zeb Colter came out to introduce Alberto Del Rio as he made his surprising return to WWE.

Since then and despite his victory and consequentially becoming the new holder of the United States Championship Title belt, Del Rio seems to have faded into the background of the roster.
There is little denying that Del Rio has a questionable connection with the crowd during his matches as WWE seem to have failed in continuing to promote him as having as much popularity as his comeback match suggested. For example, during last night's edition of Monday Night Raw, Del Rio was pitted against Goldust in what was a forgettable, few-minute match.

This bout said it all for the 38-year-old as he had gone from overcoming John Cena and taking his US Title to facing Goldust in a filler match during Raw.
Add to this the topic of money and it is easy to see why members of the WWE Universe are growing increasingly frustrated at the company's lack of direction with Del Rio.
As reported by What Culture, Del Rio is rumoured to make at least $1 million during the coming year, meaning that WWE must surely have some form of plausible plan to make the cost of bringing him back worthwhile.
In addition, Del Rio has achieved a lot outside of WWE at both Lucha Underground and Mexico's AAA promotion, which could suggest that WWE have something big planned for him in the future, causing him to come back to the company.
Something which WWE appear to have made a clear mistake with is teaming up Del Rio with Zeb Colter. Colter, who was well-known for his patriotic attitude, simply is not the right fit for Del Rio and instead so far, has added to the confusion of why followers of WWE are supposed to favour Del Rio.
Ultimately, Del Rio's return was one which was surprising and welcoming at the same time, which is rarely something the WWE Universe has seen of late.
With this in mind, WWE should continue to promote the 38-year-old as a unique individual sooner rather than later, given he undoubtedly already has the talent to prove himself as a successful heel.
