The Bayern Munich manager faces Atletico Madrid in his side's third consecutive Champions League semi-final appearance
For Pep Guardiola, three consecutive Bundesliga titles may not be enough to call his time at Bayern Munich a total success.
Having taken over for Jupp Heynckes in July 2013, he inherited a treble winning side and despite change for the better and the versatility his team has developed, the Champions League has remained elusive.
"In three years we have got to three semi-finals, but I know that people say if I don't win the Champions League my work won't be complete," admitted Guardiola.
Munich were dumped out of the competition at this stage last year by Barcelona over two legs, Lionel Messi's stunning cameo left the German champions with a lot to reflect upon. Similarly, they were blown away by Spanish giants Real Madrid in 2014 as Cristiano Ronaldo inspired the visitors to a 4-0 win at the Allianz Arena.
"I've been very lucky to have experienced what I have in Germany. I think I am a better coach, a better person, more relaxed," he said.
"In football, you have to adapt and we will adapt to get the best result we can. We know all the teams are difficult and Atletico Madrid are no exception.
"You can compare them to Barca and Madrid - when they play against the big European clubs, they can confound the favourites."
Atletico have become a dominant force in recent years, having reached a Champions League final in 2014 the same year they broke the traditional dominance La Liga.

"It has been five years since I was involved against them, but from what I have seen and what people say, they defend well, though that's not all they do," said Guardiola.
"They're extremely well organised, they've got a good structure defensively, they close space, they have a great counterattack.
"They have been fighting for the league title for the last three or four seasons as well as in Europe, so you have to do almost everything very well against them. But we will have to see what we can do in order to hurt them."
"We have to be thinking about one thing; winning."
"I am expecting a hard match against an opponent with a lot of attacking potential, against a coach who changes from game to game."
Kick-off this evening at the Vicente Calderon is at 7.45pm.
