Kane's emergence at White Hart Lane led to the Spaniard's sale last summer.
Soldado, who was sold to Spanish side Villarreal last summer, began the 2014-15 season above Kane in the Spurs pecking order.
However, the emergence of the 22-year-old, who scored his first Premier League goal of campaign in November and finished with 31 in all competitions, ultimately signalled the end of Soldado's White hart Lane career.
Kane is four goals short of last season's tally, but his former teammate thinks he's gotten even better this time around.
"He deserves it because he's a humble kid who works very hard and just has a fantastic attitude," Soldado told the Mail.
"It's his finishing that stands out - it's exceptional. Last season it seemed that every chance he got would end up in the back of the net and this season he looks even more effective."
Kane's form restricted Soldado to seven league starts for Mauricio Pochettino's side last term and the 30-year-old registered just five goals all season.
He was subsequently sold to Villarreal for a reported fee of £12 million - more than half of what he cost the Londoners in 2013.
But Soldado, who broke David Villa's minutes-per-goals record during his time at Valencia, has struggled to rediscover his goalscoring touch on the Costa del Azahar.
The Spaniard has found the net on eight occasions in 2014-15, though he has managed to contribute 13 assists for his teammates.
