The 23-year-old signed a new five-year contract on Thursday after being convinced of the Toffees' ambition. Fellaini and Rodwell have impressed at the heart of the team following Mikel Arteta's August departure to Arsenal and the Belgian believes it is a partnership which can grow.
"Ask the manager but I think if Jack Rodwell plays with me it is a good combination," he said. "Everton have good young players - Jack Rodwell has just made his debut for the senior national team. It is important to stay at a high level if you want to play with the national team."
Rodwell, who made his senior debut against Spain just under a week ago and earned his first start against Sweden on Tuesday, also believes the midfield partnership has great potential.
"It's great news (about Fellaini's contract)," he told evertontv. "He's been a magnificent player for us over the last few years and this season he's stepped it up even more.
"We are playing quite well together, we're still learning a lot from each other and we're still not in tune fully. But that will come with more games and it is a partnership that is blossoming a bit."
Rodwell himself, is not allowing himself to get carried away by his first senior call-up despite being touted as the future of the national team.
"My club performances are what have got me into the England squad on merit in the first place so I have to keep reproducing that," he added.
"I need to work hard, keep focused, keep my feet on the ground and see what happens. It's vital for me at this age to be playing games and it's brilliant for me to be able to do that at Everton.
"I'm really progressing as a player and I feel really comfortable on the pitch. I'm getting more experience every game and it's good for me to do that at such a young age."
