Moyes will be hoping to get the best out of a player who has been blighted by injuries but may be on an upward curve.
Rodwell was billed as a promising future prospect at Goodison Park and it was Moyes that established him as a regular at Goodison Park before he was sold to Manchester City in 2012.
Moyes told the Sunderland Echo: “He had great potential as a boy, athleticism and was a very comfortable football player who could do a bit of everything.
"Injuries haven’t helped him, but I also think that maybe going to Man City wasn’t the right move.
“He made that move though, and I hoped that coming to Sunderland would maybe kick-start him. Again, he has been held back by injuries, but he needs to show what he can do now."
The club, the player and the manager will be hoping this reunion can bring out the best in the midfielder who has had his fair share of misfortune that has prevented him from kicking on.
Rodwell showed signs of being able to dictate games, he was technically very good on the ball and he showed intelligence beyond his years.
As Moyes has pointed out, injuries have held him back and have prevented him from becoming a prominent player for either Manchester City or Sunderland since his move to the Stadium of Light.
Of course, a lot depends on his fitness as to whether he can revive his career under Moyes. The 25-year-old certainly has time on his side to try to get back to the form that meant he was rated so highly, and back in April the Daily Mail reported that work had gone on behind the scenes to try to get the player back to full fitness.
Rodwell should see this period as a massive opportunity to demonstrate why he was so highly thought of during his Everton days and make himself an important part of this Sunderland side for years to come.
