Jurgen Klopp and Thomas Tuchel are part of a four-strong group of managers to make history after leading their teams to the Champions League quarter-finals.
Chelsea followed Liverpool into the next round on Wednesday after cruising past Atletico Madrid 3-0 on aggregate.
The Reds had already booked their passage with a victory over Red Bull Leipzig last week as the last eight of the competition shapes up ahead of Friday’s draw.
And compatriots Klopp and Tuchel are one half of a German contingent of bosses to be involved in the next round – the first time four managers from the same country have reached that stage.
Bayern Munich manager Hansi Flick and Edin Terzic of Borussia Dortmund complete the record-breaking set after respective wins over Lazio and Sevilla.
Speaking after his side’s 2-0 win on the night at Stamford Bridge, Tuchel said: “A very good performance, unbelievable team effort, from the guys on the pitch, the bench, in the stands. You could tell that we really wanted it.
“We go through deserved. It’s a big win for us.
“Of course it’s a quarter-final which means there’s only four games left in the competition and eight teams.
“It’s a big step and it’s excellent.”
Hakim Ziyech’s goal in the 34th minute effectively sealed the tie after Olivier Giroud’s solitary goal in the first leg had given Chelsea the advantage, before Emerson’s late strike capped off the win.
The result puts Chelsea in the last eight for the first time in seven years and under a manager who took his former club all the way to the final last season.

Asked who he would like to face when his team’s fate is decided on Friday, Tuchel replied: “The draw? I am not sure that I want to come across PSG because they are strong.”
Chelsea’s progression also keeps the Premier League quota at three, with Man City also holding up their end of the bargain, while Real Madrid and Porto make up the rest of the sides setting their sights on May’s final in Istanbul.
