Former Tottenham man Sigurdsson believes Kane can go on scoring 20 goals a season.
Kane netted his first Tottenham goal of the campaign at the weekend, and speaking to the South Wales Evening Post, Gylfi Sigurdsson has admitted that he expects the young striker to continuously net over 20 goals a season.
Sigurdsson, now with Swansea, said: “Harry is very good. He always gives his all, he works very hard. He's strong, has a good shot and is a good finisher. He can be as good as he wants to be if he's given the right service and steers clear of injury. I don't see why he shouldn't continuously get 20-odd goals a season.”
Kane scored 32 goals in all competitions last season, in what was a memorable breakthrough campaign for the youngster.
Despite not coming into the first-team set-up until the winter months, Kane excelled in front of goal, and earned his first England call-up - following which he scored on his Three Lions debut.
This season, however, has been much harder for Kane, who has struggled in front of goal.
He scored for England, but when in a Tottenham shirt nothing seemed to be coming off for him, until he put the ball into the Manchester City net last weekend with a lucky finish from a rebound off the woodwork.
Many will be hoping that this goal galvanises Kane, and it is the one which allows the 22-year-old to show the kind of form he did last term with the Lilywhites.
If he does replicate the season he enjoyed last year, Kane should face no trouble reaching 20 goals this season, and in Sigurdsson’s bold opinion - that is something Kane could be doing every season for the rest of his career.
