Chelsea defeated Real Madrid 2-0 on Wednesday in their semi-final second leg at Stamford Bridge.
They sealed a 3-1 aggregate win and a place in the final alongside Manchester City.
Tuchel led PSG to last year’s Champions League final, seeing his side fall 1-0 to Bayern Munich.
When asked about this milestone, Tuchel had this to say.
“I’m very happy that we’ve achieved this,” Tuchel said.
“I’m very grateful to have the opportunity to live my life in football and this passion as a profession.”
“So grateful to do it on this level and to get to another final, I’m very grateful for that,” he added.
Tuchel has great impact on Chelsea
Much of Tuchel’s success at Stamford Bridge stems from his ability to strengthen his side’s back line.
Chelsea kept just 26 clean sheets in 84 games under Frank Lampard – managing the feat 31 per cent of the time.
Under Tuchel, the Blues have kept 18 clean sheets in 24 matches – 75% of the time.
Chelsea have now reached their third Champions League final and in all three seasons they have done so.
They sacked their manager mid-season.
In 2007-08, Jose Mourinho left the club and was replaced by Avram Grant, who helped Chelsea to the European showpiece.
The Blues fell in penalties against Manchester United that season.
The Blues also reached the 2011-12 final under a new boss.
Andre Villas-Boas sacked mid-season and replaced by Roberto Di Matteo, who led Chelsea to victory over Bayern Munich in the final.
History has now repeated itself after Tuchel took over for Frank Lampard in January.
The German has led Chelsea to the FA Cup and Champions League finals and has the club on course for a top-four finish in the Premier League as well.
