Martin Jol has questioned whether Juande Ramos can be a success at Tottenham - and admitted he hopes he can one day return to White Hart Lane.
"I'm a fighter. I still have the feeling that you never know," he said in the Sunday Times.
"I was thinking of Ottmar Hitzfeld. He left (Bayern Munich]), waited two-and-a-half years, returned. In football it's all about circumstances, opportunities.
"I realised I had to move on now and Tottenham will do fine. When I started, I said I want to have a bit of a feeling of Bill Nicholson and I was honest.
"In a couple of years I'm not sure the same people will be there (on the board)."
Of his current options, he added: "There are other clubs."
Jol defended his record at White Hart Lane, and believes he was not afford the same leeway as Arsenal counterpart Arsene Wenger.
"Wenger: fourth the last couple of seasons. Did he win something? Not the league since 2004," said Jol.
"Did Arsenal say, 'You have to win a prize or finish third?' No, because he's the man. He can say, 'I need time'.
"If Newcastle, Manchester City, Aston Villa finish fifth, you get a big celebration. Spurs is different."
Jol also had a word of warning for Ramos, saying: "With Ramos they think they can buy success, that they'll now be fourth, but that's business thinking.
"A football man would think, 'But can we be fourth? How easy is that?' Ramos was good at Seville, but can he be good at Spurs? Every club is different."
