Derby lost to Doncaster on the opening day of the season and Jewell is mindful of that as he brings his side to South Wales for the league clash – a clash that could see the Swans move into the top 6 with the right result.
However, he insists that he is bringing a team full of confidence after they recorde their first win for almost a year against Sheffield United on the weekend – a win that lifted them from the relegation zone in the early table.
And he is hoping that the win will prove to be a springboard for his side who had suffered "a crisis of confidence" after so long without a win.
Talking to the Derby Evening Telegraph, Jewell said "We go to Swansea with a bus full of confidence
"There is no guarantee we'll win but we will go there with a positive approach.
"Swansea are a good team. Like Doncaster, they have been together for a considerable amount of time, so we have to pay them huge respect.
"But the players now know they can win a match, I know that sounds mad but I said to them last week that they are proven at this level, some are proven at a higher level, some at international level. They are good players, go out and show it.
"A crisis of confidence had built up. It was a bit unfair on a lot of players who were not even here last season but have been tarred with the brush from last season, and that has affected them.
"Hopefully, that has gone now and we can go on to better things.
"In fairness to the players they have worked hard. They have taken a lot of stick, along with us all, and we know we are not out of the woods yet.
"We are not getting too carried away but I believe with the players we have we are good enough to have decent season.
"Whatever that is, I don't know. I don't want to make predictions. It is a tough league we are in but it is also a tight league. Three or four wins can put you right up there just as three or four defeats can put you in the mire.
"How much of a springboard can the win be? Hopefully, we could be looking at 10 points by next Saturday night. We will go to Swansea with a spring in our step
"The mood is bouyant but our feet remain on the ground.
"I have been saying for some time that maybe we are one League victory away from going on a run. Saturday's win was certainly a boost in confidence not just for the players and the supporters, but for the whole place.
"We know one game isn't going to change the world but it can go a long way to changing our season if we can use it as a springboard.
"I believe it can be a springboard. There are 41 games left and a long, long way to go but it is a start."
