Terry has not featured for Chelsea since his unfortunate injury in the Blues' 1-1 draw with Liverpool in the Premier League two months ago, but the England international was recently cleared for action and he will be expected to lead his side out against Brentford.
Although Chelsea are expected to comfortably beat the Bees on Sunday to progress to the next round of the competition, Terry has warned his side against underestimating Uwe Rosler's team and claims the Blues will be in for a 'test'.
"We must make sure we're up for it from the off because Brentford are certainly going to be," Terry was quoted as saying by the Sun.
"It's going to be a good test."
Terry also hailed Brentford defender Harlee Dean and revealed he was relishing the challenge of going up against the highly-rated 21-year-old.
"I see a lot of myself in Harlee," Terry added.
"It's going to be nice for us to come up against each other for the first time."
Dean himself is excitedly anticipating the opportunity of being able to pit himself against the might of Chelsea and his 'role-model' Terry.
"I've always wanted to play against John and to do so is a dream come true," Dean gushed.
"He's my idol and he's always been my favourite centre-half.
"I model myself on John - not just in tackling but with playing with my heart on my sleeve. I love a tackle and I put my body on the line and that's exactly how John plays.
"If I had half the career he's had, I'd be happy. It would be lovely to out-jump John and put one in the back of the net.
"But whether or not it happens is a different thing."
The previous round of the competition saw Brentford eke out a 2-1 win over Southend United, while Chelsea easily routed Southampton 5-1.
