Rovers have conceded in each of their games played so far in the Sky Bet
Championship, with the manager knowing that the key to success is ensuring that the goals against column is kept to a minimum.
"You look at the game the other night and it is not just about the back four and the goalkeeper," said Bowyer.
"You look at Nugent and Vardy in terms of them defending from the front, it is a team effort, and that is what we've stressed to the players.
"It isn't about pointing the finger at the back four every time a goal is scored, we've all got to be collective in that.
"We've analysed the goals that we've conceded and we've been disappointed because no-one has really cut through us in open play. The goals have all been preventable we feel.
"So we are a little bit disappointed with that.
"We've trained today and that has been the emphasis on our work has been the defensive side of the game."
