The 26-year-old scored a crucial first-half goal which sparked QPR’s comeback in a 3-1 victory over relegation rivals Sunderland in west London last weekend.
It was Remy’s third Premier League goal since completing a £8m move from Marseille in January – a club record until Chris Samba’s £12.5m deadline-day arrival.
The former l’OM star’s sparkling Hoops form has prompted France manager Didier Deschamps to include the striker in his 24-man squad for their forthcoming World Cup qualifiers.
“I’m delighted for him. It’s good for him and good for the club,” Redknapp said of the striker, who hasn’t featured for France since October 2011.
“That’s what you want when you bring players in. You want them to do well. So he’s come in and hit the ground running, got three important goals for us.
“It’s great for QPR to have someone in the French national squad.”
Redknapp will have concerns about Remy’s fitness after the striker only returned to the QPR starting line-up for their trip to Southampton after a niggling groin injury.
The Frenchman missed almost a month after aggravating the problem in a goalless draw with Manchester City in late January, and Redknapp hopes the forward will return from international duty fully fit.
“What can you do [about the potential for injury]? You hope that he’s in the squad but you also hope he’ll come back fit.”
The Premier League has a rich pedigree when it comes to prolific French strikers, with Arsenal duo Thierry Henry and Sylvain Wiltord among the best to have graced the English top flight.
And Redknapp feels that Remy could leave a similar legacy if the former Lyon youth graduate continues to maintain his impressive strike-rate and helps the Hoops beat relegation.
“If he can keep up his goal scoring ratio between now and the end of the season, he’ll give us a real chance of staying up,” he added.
“He’s scored three goals so far, if he can weigh in with another five or six goals for us, it would be fantastic.”
