Ba says chucking tungstens with his pals at home is similar to shooting at goal.
He told The Sun: "It's a nice way to relax - playing with my friends when they come to visit. It's brilliant.
"My former agent introduced me to darts by saying it was a game that would be a lot of fun.
"He knew I had to concentrate on hitting three 20s or a double or a treble - as this is a target you must achieve. Your mind is focused on accuracy.
"And it's the same in football, where I must strike the ball just to the right or left of a post. You must also be accurate to score a goal so darts is a great way of learning how to concentrate on a target."
