"To come back from 4-1 down is unbelievable," Keane said on Setanta Sports 1. "You talk about dead and buried but we showed lots of character. That's what we have in this team.
"When you're 4-1 down, you go hell for leather.
"It does feel like a sort of victory to us in many ways."
Keane insisted beleaguered Jol had the full support of the Spurs players.
He said: "You should have seen him at the end when we scored the goal. He had the support from everyone. He's shown what a good manager he is over the past couple of years.
"We're going through a bit of sticky patch at the moment."
Man of the match Gareth Bale added: "It could be a turning point from now on.
"Hopefully that last goal can kick us on and give us a bit more confidence."
