4. Grand Slam Champion
Dean Ambrose became the youngest ever Grand Slam Champion back at SummerSlam in August when he won the Tag Team Championship for the first time alongside his former Shield stable mate Seth Rollins.
Despite spending 15 years at the top of WWE's programming, John Cena has never been able to lift the Intercontinental Championship.
The Miz currently holds the Championship but could lose the title to Roman Reigns at TLC later this month if their match is a Championship decider. Reigns would then also become a Grand Slam Champion before Cena, which would give the 16-time World Champion enough of a reason to want to return and challenge the Champion at the time for the right to make the history and finally win the Championship that has always eluded him.
