The 20-year-old recently signed a new four-year deal at Stamford Bridge and joined Brighton on loan, rejecting a premanent move to Huddersfield in the process.
The loan is Brown's fourth in three years and he is well aware that chances for him to succeed at Chelsea will be limited.
"You know with Chelsea, one of the best teams in England, how tough it is for any young player," he said. "We need to win the league every year, so there is a lot of expectancy and a lot of criticism if young players have one bad game."
"It's difficult to stay in the team. They don't have time to give players a chance, so when you get a chance you just have to take it."
"It sounds bad but, with so many world class players around you, you're going to need an injury or something to a player in your position and then your chance will come. And if you don't take it you can't blame anyone."
Brown is one of five Chelsea players out on loan at Premier League sides, along with Kasey Palmer, Kurt Zouma, Ruben Loftus-Cheek and Tammy Abraham.
Will Brown buck the trend and go on to have a long career with the 'Blues'?
