"I left the club, I took my time to process everything that happened", Mourinho said.
Solskjaer is under increasing pressure, with United ninth in the EPL, 22 points behind leaders Liverpool and eight off a top-four spot, as they prepare to host Spurs tomorrow morning (Singapore time).
"Honestly, United for me is in my book of experiences, it's in my history book".
Mourinho, making his first return since being sacked by United, was stood on the touchline motivating his Tottenham players when James, fouled by Harry Winks, stumbled towards the technical areas. They are now ninth under his successor Ole Gunnar Solskjaer, but just two points behind Tottenham, who are fifth.
The Spanish club made their most significant signing of the modern era with the arrival of Cristiano Ronaldo from Manchester United, while they also added Kaká, Xabi Alonso and Karim Benzema, the latter a promising French forward at Olympique Lyon. United, on the other hand, are believed to be very reluctant to sell in January, rendering a quick move for the enigmatic Frenchman very unlikely despite the longings of Zidane, agent Mino Raiola and Pogba himself, who has described the prospect of playing under Zidane as "a dream".
Said the Portuguese: "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 understand that what they want is the exact opposite of what I want".
Mourinho, who replaced Mauricio Pochettino, said he has spoken to Tottenham chairman Daniel Levy regarding the futures of Belgium centre-halves Toby Alderweireld and Jan Vertonghen, and Denmark midfielder Christian Eriksen.
