The Tottenham Hotspur boss has been the culprit of gross player mismanagement.
No Premier League manager has ever gone without making a mistake.
Pochettino has not used the 21-year-old anywhere near enough so far this season and should be the first person to admit it - a tactic that would no doubt serve as an inspiration to the England Under-21 striker.
Instead, Pochettino is playing a dangerous game, challenging Spurs supporters...
“Is there more pressure to play Harry because he is Engish? Always,” Pochettino told reporters yesterday. “Today if we were in Argentina and he was an Argentinian player and playing with two foreign strikers, it would always be a sensitive situation.
“He is English, he is young and from the Tottenham academy, so it is normal. We understand he is a special player for Tottenham and for our supporters. My decision is always about my analysis on the training and after to give the balance to the team.”
Reports suggest Tottenham fans want Kane to start and why shouldn't they? The 21-year-old may be far from the finished product but his form in front of goal this season has been far superior to that of Emmanuel Adebayor or Roberto Soldado.
But, even if Pochettino does finally give the striker a Premier League start at Aston Villa tomorrow, it will be a week too late.
Last weekend, Kane was off the back of a hat-trick in the Europa League and the Argentine dropped him to the bench against Newcastle United. Spurs then lost that game 2-1. And what made it worse was the fact that Kane then started and scored against Brighton in the Capital One Cup days later.
That in itself was a glaring example of gross mismanagement. What kind of message was Pochettino sending to the forward by doing that? His confidence must have been shattered.
The 42-year-old blamed Kane's fitness and fatigue on the decision but, whatever the reason, Tottenham ended up losing a game they could have won had a confident, in-form striker started the game.
Now, Pochettino is reaffirming his hard-line stance on the matter. But that is another error.
The Spurs boss would be better off admitting where he has gone wrong and playing Kane more and more often. After all, he may not be the best striker in the world - but he is the best Tottenham have got right now.
