Jol told his players exactly what he thought of their defending after the 3-3 draw in a match where they were leading for most of the time following Younes Kaboul's opener.
"At 2-0 we should have scored the third and the fourth, we didn't do that and conceded from a corner," said Jol. "It's awful to see that.
"You can't concede goals like the third, from a throw-in. We have to cut out these mistakes, they make it difficult to win games.
"I can't say we are unfortunate all the time but we have to defend better. If it is a wonderful attack with lots of one-twos..... but a corner-kick?"
Jol's position at Spurs has been under scrutiny since the infamous meeting between officials and Sevilla boss Juande Ramos, and a win would have eased some of the pressure.
Victory looked assured when Gareth Bale raced through to make it 3-1, although Jol then took off skipper Robbie Keane despite setting up two goals.
"Jermain Defoe was very hungry in training and I thought he could do something," said Jol. "Robbie didn't have the best of games despite making two goals. Most of the time it comes off but this time it didn't.
"You could see he was unhappy but he better be (happy) because he's my skipper. He knows Defoe is an important part of the squad, and so is Darren Bent."
