The 27-year-old is chasing the Manchester United and England legend's goalscoring records for club and country, and his manager is confident he will reach both targets
Rooney has 202 goals for the Red Devils, 47 behind Charlton's tally of 249, and needs just 11 more strikes for the Three Lions to equal the World Cup winner's international total of 49.
And Moyes believes that as long as the 27-year-old maintains his form and fitness, the records will surely follow.
“I do think that if Wayne stays injury-free, then he will get there,” the Scot told reporters.
“If he keeps up this level of performance, he will make another big dent in the records this season.
“And, once he does that, the finishing line would look that bit closer.
“It’s a big season for Wayne for club and country and he’s started well for both. I hope he does it because it would be an incredible achievement.
“When you think of the regard in which Sir Bobby is held at this club, then, if you broke his records, it would be something which would live with you forever.
“I think it would mean Wayne would achieve legendary status, so let’s hope he achieves it.”
Earlier this month Goal revealed Rooney has rejected the opportunity to discuss a contract extension with United, and Premier League leaders Arsenal have been encouraged to bid for him in January.
