Hart, who spent last season on loan at Birmingham, is hoping England can start to win over the fans after their dismal showing in South Africa even though he has plenty of respect for Bulgaria.
And he insists England have enough talent at their disposal to be a force to be reckoned with.
Hart said: "The aim is to get back on track. We've got so much respect for the opposition. No international is easy.
"I can say that from watching quite a lot of them when not having been involved in too many. The countries that are not as easy to play against, they put 11 behind the ball, like in the Hungary game.
"But you've got to find a way to win and luckily we have got lots of winners in our team. A win on Friday can lift everyone. That is why it is huge."
Hart added: "Do I sense it's a new era? I don't know. It is hard for me to say. I don't think anything has changed too drastically.
"There are a few players who retired at the end of the World Cup but, with England. there is always fresh talent coming through.
"We are a blessed nation as regards to that and there are good young players pushing people and there are established players that sometimes get overlooked."
