The criticism he has faced this week will pale in comparison following the tragic passing Friday of his former assistant Tito Vilanova. A minute's silence was held before Bayern's Bundesliga clash with Werder Bremen on Saturday, while Pep was dressed all in black out of respect for his great friend.
"It was difficult for me to follow the match today, Tito was more than a friend," a grieving Guardiola said at full time. "The sadness I feel will accompany me for the rest of my life. We were young, we wanted to beat the world, and we did."
Indeed, as Claudio Pizarro scored one of his two goals, the camera switched to the Bayern coach staring at the floor, expressionless, hand on chin. One can imagine what was going through his mind.
A 5-2 win over Bremen will have been a little tonic for the Catalan during a difficult time, and he will now hope to overcome Madrid on Tuesday in Tito's memory.
In order to do so, Bayern will need to tread carefully. Despite putting five past Bremen on an emotional afternoon in Munich, any repeat of their first half defensive display will certainly be punished by Ronaldo and Co. Saturday's goals cannot paper over the cracks present at the back.
Much of the opposition to the use of Guardiola’s tiki-taka at Bayern has centred on the sterility of Bayern’s slow possession-obsessed game. Less highlighted has been the defensive flaws that result from playing such a high defensive line.
Karim Benzema’s winner midweek arrived in such circumstances, while Cristiano Ronaldo and Angel di Maria could have also scored due to Bayern committing so many men up the pitch.
If Madrid is afforded the same space on the counterattack that Bremen was in the opening period, then the tie could be over by halftime. Winning the ball back in five seconds may be an important aspect of tiki-taka, but Bayern cannot push as high up the pitch against the Blancos as it did against Bremen. Madrid has far too many transitional weapons in Ronaldo, Gareth Bale, Benzema and Di Maria.
There will be concern in the Bayern camp at how poorly a number of their defenders are playing. Dante was a rock in the treble-winning campaign under Jupp Heynckes, while Jerome Boateng started the current season brilliantly. Both are in poor form and committed a string of errors again Saturday.
All of which underlines the need for Phillip Lahm to play right back Tuesday. The captain was introduced at halftime against Bremen in his natural role and made a huge difference. A calming influence, who helped organize the back line, Lahm helped Bayern concede nothing after the break. Unanswered goals from Pizarro (2), Bastian Schweinsteiger and substitute Arjen Robben resulted in a morale-boosting 5-2 win.
"We won, and that's good before our 'final' against Madrid," Guardiola said.
Before the "final" is Tito's funeral, which takes place Monday in Barcelona. Whether or not Guardiola is able to attend is unclear, but beating Madrid on Tuesday would certainly be a suitable tribute.
