The defender was in fine form against West Ham this weekend and his goalkeeper is one of many impressed.
The centre back has quickly become one of the hottest properties in Europe over the last few seasons, with a number of top quality defensive displays that make a mockery of his age.
That kind of form continued at the weekend as he put in another top display, this time away to West Ham United, a game that saw him comfortably nullify the power and presence of Andy Carroll.
Howard is in a prime position to see the young star week in week out, and he says he believes Everton are looking at a world-class centre back in the making.
"I think Stonesy [John Stones] is a brilliant talent,” he told the Daily Star.
“Just to watch him, the way he glides with the ball, reads a situation. He's so young. He's only going to get better and better. I think you're looking at a world-class centre back in the next five years.”
When asked what he thinks makes Stones so special, Howard pinpointed the defender’s confidence and mentality as his strong points.
Stones has become well known as a ball playing central defender, with him often seen bringing the ball out of defence and starting attacking moves for his side.
And Howard says that mentality is what makes the top players so special, encouraging the side to take advantage of Stones’ confidence.
“He has a ton of confidence you have to enjoy it and take advantage of it,” he added.
"When you have a young player who doesn't understand what pressure is, shrugs off criticism, he's brilliant. The top players, that's what in the end make them the best - their mentality."
