The former Southampton winger has been offered fleeting chances by manager David Moyes so far this season.
Writing after Everton's win against Crystal Palace, Ball said in his column for the Liverpool Echo: "It was his first start at Hill Dickinson Stadium, a big game and he’s young, so I’ll let him off a little bit, but when he gets his next opportunity, I want to see a reaction when he loses the ball.
"We spent a lot of money on Tyler and the pressure is on him – I get it – but his job is to create opportunities and every attack I want to see a shot or a cross, that’s your job. The game seemed to bypass him which I can fully understand.
"You want to see more from your most expensive signing of the summer. You want to see an instant impact, but while he’s played in the Premier League before, he’s still a young kid.
"Tyler is in new surroundings, and he’s had to bide his time. Of course I’d like to see more from him, but we’ve also got to let him grow as a player, find his feet and trust himself."
