Manchester United are believed to be keen to recruit central midfielder Rodwell, with Owen Hargreaves having only recently returned from long term injury and Brazilian Anderson out of favour with manager Sir Alex Ferguson.
The Old Trafford supremo recently revealed that he intends to bring in one more player during the close season having already agreed to sign Fulham's Chris Smalling and Mexican starlet Javier Hernandez.
"Are we susceptible? Of course we are, because people look at us and think 'We can go to Everton and take their best players'," Moyes said in the Express.
"But if they do, they know they are going to have to come with a very big cheque. If they come here, they know it is going to be very expensive and our intention is not to let any of the players go. I expect them to be here next season."
"As far as we are concerned, Jack will be here next season," he added. "He has a four-year deal and it is being renewed just now.
"I feel he understands that he is being pushed in the right direction at Everton and he appreciates that he is at the right place."
