"We have won three from three and now we have to make the most of the opportunity on Saturday and be positive in our approach, we know we have the chance for a valuable away win," said Jenkins.
"When you are at home there is so much expectation and you are the side expected to go out and play the positive stuff.
"In the return fixture Agen are the team going to have to bring something to the game this time - they know they have to win this one.
"Agen are a quality team - as they proved at Stradey on Friday night - and are extremely difficult to break down. The big challenge for us as a team is to work on that aspect of our game during the week.
"We have to be positive about the job ahead and be realistic in our objectives and, while some of the pressure will be off us as we are playing away, it is how we react to that which will be so important.
"With us, The Dragons and Celtic Warriors all winning it was an absolutely brilliant weekend for Welsh rugby - you can feel a real buzz about the place."
