Brown has been on several loan spells over the past few years, with his most recent stint being at Luton Town.
He is still a Chelsea player, but seems unlikely to break into the first team there.
When asked about his reputation as difficult to manage, Brown said it was unfair.
He told The Sun: "I feel like a lot of people have a perception of me that I am big time. I am not big time when you get to know me.
"I am confident and I like cars. It is just a hobby but I don't do it to show off.
"People have their perception. When they really meet me then they know. It is probably because I am from Chelsea.
"When you step out in the real world is when you go out on loan. Then you really understand what football is like. I think at Chelsea they sugar coat it when you are young.
"That's why loans are so important because you can man up. When you come in the dressing room, there's no one there for you.
"They are grown men and they will tell you when you are not doing good enough.
"It was nice to get away and I did it young, and it wasn't too much for me because I wasn't at Chelsea growing up. I was at West Brom and came through their academy.
"I wasn't really in the bubble after being at West Brom but then you see other players in that bubble and you think they don't understand.
"They don't have to clean player's boots, but it is just because it is a massive football club."
