Jose Mourinho says his time at Manchester United is "a closed chapter" and he is only interested in beating them when he takes his in-form Tottenham side to Old Trafford tomorrow (HK time).
It is the new Tottenham manager's first return to the touchline at United's home ground since his sacking by the club last December.
"This is a closed chapter for me," said Mourinho, who has won all three of his matches in charge of Spurs. "I left the club, I took my time to process everything that happened, I took my time to prepare myself for the next challenge.
"Honestly, United for me is in my book of experiences, it's in my history book."
United are struggling under Mourinho's successor, Ole Gunnar Solskjaer, but go into the Premier League game just two points behind fifth-placed Spurs. "It is not for me to analyze United now," Mourinho said. "I analyze them as an opponent, how they play. How can we beat them?"
Mourinho is excited about the prospect of returning to Old Trafford.
He said: "I feel good, I like to play big matches, I like to play against the best teams and go back to a place where I was happy.
"I have a great relationship with the Manchester United supporters. I went back as a pundit and I was humbled by such a beautiful reception.
"Tomorrow I go back as the coach of the team that will try and beat Manchester United.
"I understand that what they want is the exact opposite of what I want."
Solskjaer, meanwhile, said he does not fear for his future as United manager despite a spate of sackings in the Premier League.
Spurs turned to Mourinho after dismissing Mauricio Pochettino last month, while Arsenal and Watford have subsequently sacked Unai Emery and Quique Sanchez Flores.
