#4 Lashley
While the WWE has yet to make a formal announcement, it seems fairly certain that former Impact star Lashley has signed a new deal with his former company.
Lashley always felt like the one that got away from the WWE. A superstar who, despite several pushes, never quite managed to get over in the way that WWE creative had envisioned. Fast forward nearly a decade and after a successful run in Impact, Lashley looks like the kind of star the WWE always wanted him to be.

Rumours a few weeks ago suggested that Lashley was likely to feud with Lesnar upon his return to the company, but if Lesnar decides not to stay with the WWE, logic would suggest that a feud with Roman Reigns would be the next best bet for the former US and ECW champion.
Lashley will return to the company with a lot of hype behind him, and having him instantly compete for the Universal Title against Reigns would automatically re-establish him as a major star within the company.
