Chelsea boss Mauricio Pochettino accepts there's a section of the support skeptical about him.
Pochettino knows his Tottenham background works against him for some Blues fans.
He said, "I like your question. It's normal. I came from a different club but it's normal. You need to convince. You arrive at Chelsea in a project that is different to the last 20 years. I played with my reputation to come here also, in a project that is to build a team with young talented players with the possibility of the potential to become top players.
"For us, we knew that was a massive challenge. A challenge of building a team, winning games, being competitive and to take the risk with the fans. But I'm not going to be a populist. I said from the beginning that I want to build a genuine relationship – not to kiss the badge or to do stupid things on the touchline to win the benefit of the fans.
"What I want is to provide to the team the tools to win games, believe in ourselves and build a very good relationship. I am not here to be a populist or a hypocrite and say 'Oh I love the fans' because I know, always it is about time to build this relationship."
