John Cena has had an amazing retirement tour, and it is closing in on its final day, which is set for December 13th, at Saturday Night's Main Event. He has done almost everything that was possible for him during this retirement tour. He won the men's Elimination Chamber match, he won his record breaking 17th World Championship, and he even turned the heel for the first time in 21 years.

The only thing that was remaining was becoming a Grand Slam champion. He worked as a mid card during his early career, and he won the WWE United States Championship a number of times. Since he was exclusive to SmackDown during his early career and WWE was conducting a hard split, he did not get to win the WWE Intercontinental Championship, as SmackDown only had the United States Championship.

John Cena set a new record on RAW last Monday

From 2005, he started working as a main eventer he never looked back. He did win the WWE United States Championship even after becoming a main eventer, but surprisingly, he never got the opportunity to win the WWE Intercontinental Championship, and it was the only thing that was preventing him from becoming a WWE Grand Slam Champion.

John Cena is now a WWE Grand Slam Champion

After achieving almost everything during his retirement tour, he only had one thing left, and that was becoming a WWE Grand Slam Champion. In order to do that, he needed to win the WWE Intercontinental Championship. So WWE officials decided to give him the Intercontinental Championship, and history was made last week on Monday Night RAW.
