Chiefs just lost out to Mamelodi Sundowns for the services of Bafana Bafana midfielder Andile Jali, while their arch-rivals Orlando Pirates caused a stir by announcing nine new signings on Monday, which included the capture of goalkeeper Brilliant Khuzwayo, who turned down a contract extension offer at Naturena.
Amakhosi were also said to be targeting CAF Champions League winner Patrice Carteron as a contender to replace the departed Steve Komphela, but the French coach has ended speculation over his future by taking charge of Egyptian giants Al-Ahly.
McCarthy, who won two league titles in a five-year spell with Chiefs, presumes the Soweto giants are making moves behind the scenes in a bid to end the three-year trophy drought under Komphela.
"Maybe before the pre-season starts or maybe a week in pre-season [Chiefs will reveal signings]. Definitely knowing Chiefs, they want to keep it a surprise, they want to come up and make headlines," says McCarthy.
"I just hope that whoever they're busy negotiating with or have already sealed a deal with will be somebody like, in my opinion, that needs to be strong in terms of character.
"He [the new coach] needs to be very strong in terms of experience. He needs to be a coach where you can say he's a father figure, he's a mentor, he's everything that a coach is. When he goes to a game he knows his job, he can change.
"I don't like to say coaches are good, but I see a good coach when he can take a team of players to the next level from where they are, from when he signed them or found them."
