The former Inter player was attracted to the Valencia-based outfit because of their ambition, while seeing Sergio Ballesteros beat Cristiano Ronaldo in a sprint also impressed him
Since his transfer, the powerful forward has netted two goals in three Primera Division games, including scoring the winner against Real Sociedad on his debut.
"I was attracted to Levante because of their ambition. I'm the first to admit that things didn't go well for me at Rubin Kazan, but I think I have made the right choice in coming here," the Nigerian told Marca.
The former Newcastle man attracted interest from a number of clubs in the last transfer window but Martins was also drawn to the Costa Blanca outfit after seeing Cristiano Ronaldo out-sprinted by defender Sergio Ballesteros.
"In a match against Real Madrid I was amazed to see Cristiano Ronaldo beaten in a sprint by an old man," he added.
"I asked myself who is he, and how could he run that fast? It turned out it was Ballesteros, who I know well now and is an incredible player to still be playing.
