Lotito hailed Reja after the long-awaited victory over Roma.
"Tonight Lazio proved they can challenge anyone and deserved the win, especially in the second half. With so many chances, hitting the woodwork twice and forcing saves, at the end we did it," he grinned on Sky Sport Italia.
"I defended Reja because I consider him to be the right person for Lazio, despite all the criticism and protests. This evening I was proven right.
"This derby win was worth four altogether."
