The Red Devils centre-back has not been part of any of Hodgson's squads since he took the national role prior to last year's European Championships.
"I don't think [the England snub has affected him]," the Daily Star quotes Giggs as saying. "We're just happy that he's playing so well for United.
"England's loss is our gain. The rest of the stuff we're not too bothered about as long as he keeps putting in performances like that."
Meanwhile, United are on course to reclaim the Premier League title due to their 12-point lead in the table.
