Ghana assistant coach says the Black Stars could soon be deploying a three-back system in their bid to have more options in tactics.
The four-time African champions, like most teams, use the traditional system of four flat defenders consisting of two centre-backs and two full-backs.
The three-back option, which has gained popularity in recent years, though, deploys three-flat centre-backs, with the ‘full-backs’ operating slightly higher up as “wing-backs”.
“The three-back system is a system you would always want to have as an option.
“It’s one of those systems that you need to have in mind, even in a game situation where you need more midfielders, you can sacrifice one defender. It’s a good thing.
“We’re going to work on that so that when it comes that we have to use it, it won’t be a problem.
“All our defenders already have experience with that so it’s going to be one of our options.”
During May’s friendly against Japan, the Black Stars briefly played a three-back system following the substitution of injured Rashid Sumaila.
Appiah’s side, who saw this month’s 2019 Africa Cup of Nation’s qualifying double-header against Sierra Leone cancelled, return to action in November against Ethiopia.
