Nigel Pearson refused to get dragged into Bristol City's two penalty claims but praised the response of his side after Tuesday's embarrassing defeat against Lincoln.
The Robins dominated from the first whistle against play-off hopefuls Watford and did everything right apart from failing to make their chances pay. Tommy Conway missed a golden chance in the second half when he dragged an effort wide of the target when through on goal.
Andi Weimann also came within inches of breaking the deadlock when his header was superbly tipped around the post by Daniel Bachmann. City were on the receiving end of two controversial penalty decisions in the opening 45 minutes involving Nahki Wells.
