The Catalan won the Europe's elite competition twice in three years during his glittering stint in charge of Barcelona but has now gone nine years without making the final.
He could only reach as far as the semi finals at Bayern Munich, while he's been knocked out at the quarter final stage in each of his four years in charge of Manchester City - the most recent being a dismal 3-1 defeat to Lyon in Lisbon.
There are a whole host of different factors and details as to why he's failed in Europe - with many claiming that Guardiola simply had it easy at Barca as he had three of the best players in the world at their absolute peak.
But interestingly Guardiola himself is happy to admit just how lucky he was to manage that crop of players.
"What do you say to people who claim you've not won the Champions League since Barcelona because you don't have Messi, Xavi, Iniesta..."- Football on BT Sport #Club2020 (@btsportfootball) August 15, 2020
"I completely agree!"

Asked about the claim in his post-match press conference on Saturday, the 49-year old replied: "I completely agree with them!
"When I was there I said many times that we win because I have incredible players. But I had in Munich and in Manchester as well. In Barcelona I was a lucky guy, I'm sorry! I agree with them."
Individual errors cost the Blues again, with a five-yard Raheem Sterling open net miss to equalise and a spillage from Ederson that allowed Moussa Dembele to score his second and seal the result, happening 59 seconds apart.
Reflecting on another miserable Champions League exit, Guardiola said: "One day we will break this gap to the semis. In the first 20, 25 minutes we struggled to find spaces to attack.
"The second half was OK - we were there. I had a feeling we were better. You have to be perfect in this competition.
"We did a lot of good things, but it wasn't enough. We made mistakes in the boxes in key moments. We struggled to find our spaces to attack.'
