Harry Forrester has fired a warning at FA Cup opponents Chelsea.
Brentford have hope of completing an unlikely giant-killing at Stamford Bridge on February 17.
Bees hero Forrester, whose penalty almost secured him a place in FA Cup folklore, said: "It's not impossible. I think people would've said drawing here was impossible, to get a result against the European champions."
The striker revealed he had expected more from Chelsea yesterday following their Capital One Cup exit, adding: "They went out of the cup at Swansea in the week and we thought we might have got a bit of a backlash."
