The 30-goal striker was named PFA Young Player of the Year at the PFA's awards night in London.
His performances were also recognised with runners-up in Player of the Year and a place in the PFA's Premier League Team of the Year.
“It was a well-deserved honour for Harry, I fully expected him to win the Young Player award and also Eden Hazard the Player of the Year, although I think Harry was close to winning the main honour too," said Jan, who was named in the PFA's Team of the Year in 2012-13.
“Harry has had an excellent season, he works so hard. I wouldn’t say I am surprised at the progress he has made because I know his qualities, I play against him every day in training and I know what he is capable of.
"Instead, I am just really pleased that he has been able to reproduce that talent on the biggest stage and in the big matches for us.”
But it’s not just Harry who came in for praise from Jan.
While the frontman has earned all the plaudits for his impressive goals haul, we became the first team in the Premier League this season to have three players reach double-figures, with Nacer Chadli and Christian Eriksen following in Kane’s footsteps.
“Again, that is fantastic for the club and the players involved,” said Jan. “It’s a big achievement for Nacer and Christian and as a team, it is always good to have more goal threats from other areas than just the strikers.
"We’ve certainly been a more attacking side over the second half of the season and we’ll be looking to continue that over the last few matches.”
