Fans had many expectations heading into Sunday night's Elimination Chamber pay-per-view, fueled largely by Internet speculation.

Rumors had been running rampant of returning superstars, changes to the world title matches and the addition of undercard bouts to round out a four-match card.

In the end, some of the expectations proved true while others ultimately failed to materialize.

Two injured superstars returned from injury -- albeit in an in-ring segment rather than matches -- while Santino Marella proved doubters wrong and Jack Swagger defended his United States Championship for the first time on pay-per-view.

Both world champions also retained their titles, and the stage seems to have been set for WrestleMania.

Overall, WWE produced a solid pay-per-view that won't be remembered as the best of the year, but it likely won't be the worst either.

Here's a match-by-match look at the show:

WWE Championship Elimination Chamber

CM Punk vs. Chris Jericho vs. Dolph Ziggler vs. Kofi Kingston vs. The Miz vs. R-Truth

Five of the six men in this match showed a lot of fire and drive in the match, which was given the opening slot on the card. While Kingston and Ziggler were among the early eliminations, both young stars shined bright. Kingston's leaping DDT off the cage onto Ziggler may have been the spot of the night. But don't take this the wrong way, all these men did more than just provide big spots; they worked a solid match that kept the crowd engaged for the duration. Punk and Jericho continued to work well together, and Jericho's removal from the match due to injury sets the stage perfectly for Y2J to claim he never truly lost the match, thus establishing a singles match at WrestleMania. R-Truth was the only one who didn't really have the chance to shine, but with so much star power in the match, someone had to be the sacrificial lamb.

Other highlights of the match included Punk showing the severity of his issues with Jericho by releasing the Anaconda Vice he had applied on The Miz to enter a staredown with Y2J, Jericho retreating to the pod to escape Punk, Jericho slamming Punk's limbs into the pod door, Jericho's continued assault on Kingston after eliminating him from the match and Miz scoring a nearfall on Punk following a Skull-Crushing Finale. That's a lot of Punk and Jericho, but really, is anyone surprised by that?

Divas Championship

Beth Phoenix vs. Tamina Snuka

These two women unsurprisingly put on a solid divas match. Many people will bash and trash it simply because it's a divas match, but both women worked hard. Tamina looked strong for at least being able to hit her finisher, though Phoenix kicked out at two. Phoenix followed up with a Glam Slam for the victory. This match was better than most divas matches in 2011, but it will be interesting to see what’s in store for Phoenix at WrestleMania.

John Laurinaitis Announcement

Laurinaitis came to the ring to announce that several superstars have been filing complaints against Smackdown General Manager Teddy Long. He was soon joined by the returning Alberto Del Rio and Christian, as well as Mark Henry. Not much came of this segment other than the returns and Laurinaitis announcing his intentions of becoming general manager of both Raw and Smackdown. I have to question why this segment received time on the pay-per-view while the tag team champions were left on the sidelines.

World Heavyweight Championship Elimination Chamber

Daniel Bryan vs. Big Show vs. Great Khali vs. Cody Rhodes vs. Wade Barrett vs. Santino Marella

Anyone who questioned Marella's inclusion this match needs only look at the reaction he received from the Milwaukee crowd to see how it was justified. The match seemed to be dragging on, and the crowd was chanting "Boring" up until Marella entered the bout. "The Milan Miracle" managed to eliminate both Rhodes and Barrett from the match, albeit with assistance. Marella stood out as the real star of the group, as he came in with the lowest expectations and exceeded them by leaps and bounds. Khali's presence was treated as a joke, as he was eliminated in 45 seconds, negating the build he received. Rhodes and Barrett gave solid performances, and Bryan continued to shine in his role. After the match, Sheamus officially sent a message to the champ to prepare for WrestleMania. Weird, yet amazing, to think that last year's dark match will be repeated as a world title match this year.
