Hull City boss Phil Brown admits Chelsea are still vulnerable to set-pieces.

For their 1-1 draw on Tuesday night, Steven Mouyokolo put the Tigers ahead as he left the Chelsea defence for dead to head home a Stephen Hunt corner after half-an-hour.

"It's my job to investigate how to score goals against Chelsea and they've conceded something like nine out of 10 of their goals, or something like that, from set pieces," he said.

"If that's the Achilles heel for Chelsea then we have to exploit it."
