Speaking to the Lancashire Telegraph the bargain signing from Porto last Summer said he would love to play under Mark Hughes for the rest of his career.
"I can definitely see myself playing under Mark Hughes until I finish my career.
"I've been fortunate to play for two managers who are very similar in terms of being laid-back and easy going, and they are able to get the best out of you.
"One of those was Jose Mourinho, and Mark Hughes is very similar.
"He's young and full of energy, and he wants to achieve a lot of things.
"For a player like me, it's great to be playing for a manager who is so optimistic about wanting to achieve things, and wanting to win things.
"You just want to be part of all that, and I can see myself easily playing for a manager like that for the rest of my career."
McCarthy's performances have come under scrutiny this season as he struggled to recapture the form of last season in a slightly different role with his new partner Roque Santa Cruz. Despite this, the fans have stuck by McCarthy.
It was rumoured in the Summer that he would leave in order to find Champions League football, however, McCarthy has conceded that he is unlikely to find regular first team action at a club where he is guarenteed to play in the competition.
"The club has been nothing but generous to me. They've given me an opportunity that not many other clubs would have given me in the Premiership and I feel I'm repaying them.
"In all fairness, the only way you can repay them is by pledging your future.
"I think my shot at playing in the Champions League has gone if I don't make it with Blackburn.
"If we can't do it then there's probably only four teams where you are guaranteed an easier run of playing Champions League football.
"Either you go to United, you go to Chelsea, or Arsenal, or Liverpool. If you go to any of the other clubs then your chances are limited.
"Blackburn are right up there with the rest (outside the big four)."
Manager Mark Hughes added: "I really feel he wants to stay here. "He's under contract but we want to make Blackburn Benni's club.
"It could be the last big contract of his career, you could never say. But we'd love for him to stay here for a long time.
"Technically, and in terms of manoeuvring the ball, he's as good as there is and if we can get him in the right areas then he can produce."
