The Spurs striker has dominated the headlines this week for his absence at Hotspur Way when the club were expecting him back on Monday.
It is widely thought that Kane is trying to force through a move to Manchester City in a stand-off with chairman Daniel Levy, who remains reluctant to strike a deal.
However, while refusing to detail the specifics, the England captain yesterday insisted he would 'never' refuse to train and will return to Tottenham 'as planned' on Saturday.
Not everyone has bought the 28-year-old's side of the story, especially ex-Spurs centre-back Vega.
Responding to the news on Twitter, the Swiss knocked up his own version of Kane's letter.
It read: "It's been almost five days since I refused to train with the club and I'm hoping this message will fool you all.
"The truth is, I thought I could force my way out of the club. I done f***** up, lads.
"While I won't go into the specifics of the situation, this Messi fella has ruined my plans.
"Tottenham fans are always supportive, so in the words of the late Tom Petty, I'm crawling back to you."
But a number of Kane's former teammates have defended their pal's professionalism.
"Whoever know you knows what kind of professional you are," Erik Lamela posted in a comment below Kane's statement on Instagram.
"Keep your mind as always, my friend," he added.
Joe Hart, meanwhile, wrote: "Top pro above all H."
And whatever the truth of Kane's actions, talkSPORT pundit Tony Cascarino believes the blame ought to be laid at Tottenham's door for failing to keep their house in order.
The transfer speculation surrounding their star striker is just the latest saga in a summer which saw them make a mess of their search for a new manager.
Following the sacking of Jose Mourinho and Ryan Mason's interim reign, Spurs failed in pursuit of numerous targets before eventually landing on Nuno Espirito Santo.
Cascarino said: "Mason, a 29-year-old, taking charge of the club? Nothing against Ryan, he may prove to be a coach one day, but giving him the reins - Harry must've been incredibly disillusioned about what's going on behind the scenes.

"Nuno is the strangest one of all. They chased many, many managers and didn't get one over the line.
"Then they got Nuno and only gave him a two-year deal. That's not stability at a football club, or thinking they've got the right man.
"Tottenham should have the right man they really believe in."
