Both sides have lost their opening two encounters this season.
But Jon said: "We have tough games coming up, but I am confident that we can set the record straight before we come to face England.
"It is going to be a big test for us and Italy are a good side, but they got beat by Wales."
The Welsh are also in opposition before the Calcutta Cup match at Twickenham.
"It's a good test of strength for us as players to come back and I am pretty confident we can do that," said Jon after the weekend defeat by Ireland.
"We put great pressure on ourselves and there is also pressure from the people who come and watch us.
"It's important that we start winning and we have to start doing that as soon as possible."
