Lollichon wasn't part of Chelsea during Mourinho's first spell in charge.
"Mourinho is, I think, happy to work with me – that’s good," Lollichon told the Daily Mail. "And I am happy because it is my eighth coach in five and a half years.
"I saw the front page of l’Equipe, before PSG appointed Laurent Blanc, there were five candidates. I have worked with three. I said 'wow'. It is crazy.
"It is very exciting. He is a very important coach and a massive man. It is very exciting to have another experience."
