You guys are making scratch my head.
Pep's tiki taka turned everyone's head in 2008 to Barcelona. They were the most enjoyable team to watch. They scored the most goals during the group stage. Went on to beat Bayern 5-0. Not to mention, they were mostly the same group of players that failed miserably under Frank Rijkaard.
Chelsea was having a bad season and everyone expected Barca to rule them.
Garndpa Guus parked the bus and showed the world how it's done. By some miracle, Barca won. But that match changed how every team played against Pep until this day, just park the bus if you want to have a chance.
One time, Murinho tried to not to park it against Barcelona and RM lost 5-0. So he sticked to what Guus Hiddink taught us thereafter.
Don't blame Pep if you are bored, the other team is certainly not the football you would like to see. Nothing to do with Pep. Although, he has learnt a few things on how to deal with these situations, it showed when they played against Juve and Atletico.
