Kaizer Chiefs FC defender Aden McCarthy's buyout clause has been triggered by Azerbaijani side Sabah FK, taking his transfer to Europe a step closer. According to SABC Sport, the activation of the release clause represents a major breakthrough in the deal. McCarthy's departure has been anticipated for several weeks, but the activation of the release clause has effectively cleared the path for his transfer to Europe, subject to a successful medical. The 22-year-old's personal terms with Sabah are understood to have already been agreed. McCarthy enjoyed a breakthrough campaign in the Amakhosi first team this past season, making 31 appearances across all competitions. His brilliant displays for Chiefs at the back attracted interest from overseas clubs, including Sabah FC, who have now won the race for his signature. In anticipation of McCarthy's departure, Chiefs have already moved swiftly to find his replacement by acquiring the services of highly-rated defender Thabo Moloisane, who joins Amakhosi on a free transfer after leaving Stellenbosch FC.
