The French midfielder slapped Kane’s face after an altercation between the pair and could have no complaints when shown a straight red card.
Everton’s self-destruction didn’t stop there as moments later Keane foolishly dived on Christian Romero to concede a penalty.
Kane sent international teammate Jordan Pickford the wrong way for his 24th club goal of the campaign.
“Departing changes the sentiment, but our mindset is growing up all the time,” said Ditchie.
“They’re pushing their own standards way too high, even going down 11 vs. 10 as we continued to play,” he added.
Tottenham failed to make the man advantage count in the closing stages as they invited Everton in search of an equaliser, before Lucas also saw red for a tough challenge on Keane.
Everton’s fightback was rewarded when centre-back Keane raced forward before curling a powerful strike into the top corner.
