Morata has spent the second-half of the season on-loan with Atletico Madrid.
The 26-year-old scored 24 times in 72 appearances for Chelsea but has rediscovered his eye for goal back in Spain.
Morata has found the back of the net six times in 15 La Liga appearances for Atletico.
Former team-mate Hazard looks set to join him in Madrid, but across town at Real instead.
Morata believes he will prove himself a star at the Bernabeu.
"He is one of the best players in the world and can fit well in any team, the team he wants. [He] is a top player and a top person," he said.
