Chelsea boss Mauricio Pochettino has paid tribute to Tottenham chairman Daniel Levy.
Pochettino returns to Spurs for the first time since Levy sacked him four years ago.
But the Argentine said: "For me, the most important person because he gave me and my coaching staff the possibility to be in Tottenham. Not only a professional relationship also a friendly relationship.
"Too many memories together, spend nearly six years together, it was an amazing journey. Only to say thank you for the opportunity to be there working, to experience great things, like to build the new stadium. We were talking before about in one season playing in White Hart Lane, Wembley and MIlton Keynes.
"Three stadiums in the same year, that was amazing to be part of, a small part of an amzing project, only I can say thank you."
Asked if he was close to returning last season, Pochettino added: "No and after we finish our relationship with Paris Saint Germain, we wanted to be one year away from football and then arrived the offer from Chelsea."
