Former Tottenham striker Roberto Soldado believes there are no limits to what Harry Kane can achieve in the sport.
Kane is already one of the most prolific strikers for England and in the Premier League.
But is easy to forget he still has so much of his career in front of him, and Soldado believes Kane is not quite at his peak.
"I always say that if there is one period of my career I'm not happy with, it's my time at Tottenham," Soldado, a former Spurs player, said in an interview with The Guardian.
"I also had Harry Kane's boom to contend with, I understood perfectly because you could see it from the start.
"I saw his level in training and it was amazing. I don't think there's a limit to what he can do; we still haven't seen the best of Harry Kane.
"When we did shooting drills… pfff. With both feet, he was prolific. He plays so well back to goal, gives assists, is intelligent, thinks quicker than before.
"Maybe he had struggled this season because the team wasn't having the best time, but he's continually improving."
