Both wasted gilt-edged chances to mark their first starts at senior level with a goal and they also had other opportunities to find the net at Wembley.
Otherwise, they performed reasonably well in what was England's first win over the Swedes for 43 years, but while Everton midfielder Rodwell was upbeat about his contribution, Fulham forward Zamora was decidedly less so.
That is despite the latter appearing to have a much greater chance of earning a place in Fabio Capello's European Championship squad providing the likes of Jack Wilshere and Steven Gerrard are fit.
Rodwell, who seems far more likely to be named in Great Britain's Olympic party, said: "All in all, I'm pleased.
"I managed to get in a few goalscoring positions but I felt like I should've scored maybe one or two."
Indeed, Rodwell somehow managed to send a header against the post from barely four yards.
Yet, he shrugged off the miss, saying: "Nine times out of 10, I'd have put that in the back of the net.
"I'm getting in the positions. I got in another couple of positions to get my shot in on goal as well, so I'm pleased."
Zamora, who fired into the side-netting with an almost equally presentable opportunity, dubbed his own performance "not the greatest".
He added: "I'd have liked to have put one of the two chances I had away.
"It's hard up front on your own, really.
"You've just got to work hard and try to put yourself about and that's what I tried to do.
"If I could nick a goal then that would've been brilliant.
Asked if he needed a goal to prove his international credentials, he added: "Always helps, I'm sure."
Rodwell, who also came off the bench in Saturday's shock win over Spain, refused to contemplate the prospect of gatecrashing Euro 2012, saying: "Next summer's a long way off and I'm not really thinking about that at the moment. I've got a lot of games before that.
"Obviously, getting a couple of games under my belt, it gets you the feel for it and you want as much as possible.
"The main thing is my club form and getting as many games as possible.
"That's obviously what got me the reward of the senior call-up.
"So, if I keep my feet on the ground and keep working hard at Everton then hopefully there could be more to come."
Zamora said: "I've just got to work hard at Fulham, keep doing what I'm doing.
"Obviously, the gaffer will be looking and watching and that's all I can do."
Zamora will be 30 when Euro 2012 begins, arguably his one and only chance to play in an international tournament.
The likes of Danny Welbeck, Daniel Sturridge - and possibly Andy Carroll - look certain to come to the fore in the build-up to the next World Cup.
That could also be the case for Rodwell, who played with Welbeck and Sturridge at this summer's European Under-21 Championship, along with Kyle Walker and Phil Jones.
Rodwell said: "The list goes on and there are a few more under-21s that can play as well.
"We've got a good bond.
"The squad, anyway, are good lads and they all welcomed me, the senior lads.
"There are a lot of youngsters, so they helped me as well.
"So I felt really comfortable as soon as I got with the seniors."
