Thomas Tuchel has revealed that he sought advice from Jurgen Klopp before making the move to the Premier League.
The Chelsea boss succeeded his compatriot at Borussia Dortmund back in 2015.
He and Klopp have since met on several occasions in European competitions.
They will now meet in England’s top flight for the first time with Tuchel admitting he discussed the league with Klopp and Pep Guardiola.
That meant that when Chelsea came calling he was primed and ready to take up their offer.
Klopp and Guardiola have won the league during their time in England and the Blues boss believes their teams are “the benchmark”.
Chelsea and Liverpool are embroiled in a battle for the top four this term and a win for the Blues would see them move four points clear of the outgoing champions.
“No, it was pretty clear what I expected from the Premier League,” he said.
“I mean, I was talking to him and talking to Pep regularly and got their feelings about it when we would meet when I was the coach in Dortmund and in Paris and we’d meet in the Champions League or at [Uefa] coach’s meetings.
“The feedback was always pretty clear and so I stepped into this adventure without his advice.
“If I called him I hoped he would have called me back, because he does not want to play against me but I’m not sure! No, I’m just joking!
“It’s nice to meet him, it’s always nice to meet him. It’s super hard to play against him and his teams.
“For me Liverpool with Jurgen and Manchester City with Pep are the two teams who are the benchmark, the teams we have to close the gap to.
“This is our target and we are fighting hard for this. And I don’t feel like I fight alone. I have a strong club behind me, and a strong team at my side, so it feels good.”
