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 penned a 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."
