Wenger said: "It's sad because he had no real chance to be successful. He was not given the chance to turn the crisis around. He had two very good seasons and in his third he had a bad start.
"He had two fifth-placed finishes in the Premiership, which isn't easy because there are other big clubs. It looked, right from the start, that he didn't get the complete confidence from inside the club and then it becomes difficult.
"A new manager will not be under the same pressure because they will have to give him time.
"Tottenham would have come back, no matter what they had done - they would not have stayed in the bottom three for the whole season. When they get Ledley King and one or two others back, they will come back."
