The 20-year-old was a target for a host of clubs last term after bursting into the O's first team, but following talks with Slade he instead penneda new contract in February keeping him at Brisbane Road until 2015.
"The manager said I needed to be playing first-team football at my age and that he didn't think I'd get that elsewhere and that I wouldn't want to be playing in the reserves because I'm better than that," said Odubajo.
"It was a great feeling knowing that he trusted me that much in my first season in League One, so I owe it to him."
Odubajo opened his goalscoring account this term in the 3-0 win over Shrewsbury on Saturday which kept Orient at the top of the early-season table.
He added: "I feel like I've started to improve my end product which wasn't the best at times last season, and I want to score more goals too."
