The tournament debutants held their own against a highly rated Belgian side in the first half in Sochi before a stunning volley from Dries Mertens and a Romelu Lukaku brace after the break helped the Europeans climb to the top of Group G.
Panama are bottom of the group on goal difference and need a positive result against England in Nizhny Novgorod on Sunday to retain any hope of progressing to the knockout stages.
"For me, Belgium are a more difficult opponent than England," Rodriguez was quoted as saying by The Telegraph.
"England are a big team with very good players but we will try to win. I watch Premier League football every week... It is fantastic to play against some of those players and I will try to have a good game.
Belgium manager Roberto Martinez expressed concern over potential injuries emerging from Panama's hard tackling but defender Roman Torres says his team will continue to be aggressive to counter a speedy England side.
"Football is like that -- you always have to impose yourself, you have to mark out your territory," he said. "I think we competed well against Belgium, and I think when there were tackles, they got stuck in just as much as we did.
"England are a bit more direct than Belgium. They try to make use of the pace they have. We'll need to be compact and limit their space."
England are second in Group G after their 2-1 win over Tunisia on Monday. (Reporting by Aditi Prakash in Bengaluru; Editing by John O'Brien)
