In the week preceding his League Two side's 3-1 third round win against Newcastle on Saturday, Westley rammed home the story of `David and Goliath' and how the little Israelite had defeated the giant champion of the Philistines by design, not by chance.
It explains in part the physical desire and the energy with which Stevenage overwhelmed their Premier League visitors and gained sweet revenge for their famous fourth round knockout by Alan Shearer's Newcastle 13 years ago.
Westley said: "I don't think you win if you don't expect to win. We talked beforehand about David and Goliath. We talked about the fact that David had a plan. David knew what his strengths were. David didn't play Goliath's game. He played his own game.
"And we went out there and played our game and got the result by doing that."
