For a one-season wonder, Harry Kane has had a decent couple of years following his breakthrough season in 2014/2015.
The Tottenham striker is now on 99 competitive goals for Spurs and it would be hard to imagine him not breaking the century barrier at the start of the season. But it is the end of the season where most fans of England want to see the big striker still banging in goals – when England travel to Russia for the World Cup.
Kane is out on his own as England's No.9 now, and any chances England have of getting beyond the group stages or – dare we dream – past the quarter-finals, are likely to rest on his broad shoulders.
And although he was disappointing by his own admission at Euro 2016 in France last summer, there are high hopes that he can carry some momentum from his club form into his country's cause next summer.
“He's not just an out and out goalscorer, but a great player too, and he's getting better and better,” says Heskey.
“People said he was a one-season wonder, but he did it again and again – and don't forget last season he missed ten games or so and still finished top scorer.”
Indeed Kane's record last season of less than one game per goal in the Premier League was the best in the division, and he led the stats on shots attempted, shots on target, goals and assists combined, and more.
Comparisons have been made with Alan Shearer, the last Englishman to regularly score 30 league goals in a season, and Heskey says that should be Kane's challenge now.
“The next step for him is getting 30 goals in one season, and to keep going from strength to strength. It's great for Tottenham and great for the national team as well,” said the former England forward.
And there is no doubt that he will be a Tottenham great, according to club legend Gary Mabbutt. The former Spurs captain played alongside the likes of Gary Lineker, Teddy Sheringham and Jurgen Klinsmann in his time at Tottenham and reckons Kane is as deadly as those three already.
“What Harry has done over these past few seasons has been immense,” said Mabbutt.
“I played for Tottenham for 16 years and been involved with the club for 35 years, and in that time I have played with and seen some of the best strikers in the world. Harry is one of the best finishers I have ever seen, and definitely in the same bracket as those three.”
Perhaps the most surprising thing about Kane is his development since his early days as a raw teenager, playing sporadically for Spurs and then on loan at Millwall, Leicester and Norwich. Although he always had good ball skills and tremendous finishing ability, there were doubts even among Tottenham’s youth coaches that he would make the grade because he lacked the pace that most top strikers possess.
Les Ferdinand, one of the greatest forwards in Premier League history, worked with Kane at Tottenham’s youth academy and shared those doubts. “He was a fantastic finisher but he just seemed to lack that yard of pace, and that was our only concern. Somehow he managed to work on it and get quicker of the mark.”
While Kane is still not as quick as say Thierry Henry at his peak, like Shearer he is quick enough and has the strength to hold off defenders. He also has the knack of arriving where the ball will be, and a willingness to shoot on sight, usually with power and accuracy. And he is a very good header of the ball too – the complete package.
“I see him in training and I see him in matches and he's a great all round striker,” says Mabbutt. “He gets great power in his shots, from very little backlift, with both feet, he's good in the air, and there are always goals likely to come from him.”
