Barca and the Blues played out a goalless draw and the tie is all set for a thrilling finale next week, but Pep is not happy at all with what happened in Camp Nou...
The Blaugrana boss hit out at the referee for booking his players and not protecting them, while also criticising Chelsea's negative and physical approach to the encounter.
Referee Wolfgang Stark received the first round of criticism from the disgruntled Guardiola as he stated that the man in the middle did his team no favours.
"Referees need to take a look at themselves," the coach fumed. "We looked to score, did not commit many fouls and we should have been rewarded.
"Toure was booked for protesting about a free kick. Chelsea repeatedly fouled, with [Andres] Iniesta being kicked a lot.
"The experts claim that games in the Champions League are decided in the details and this has not helped us."
Chelsea's tactics were next as Guardiola explained that Barcelona found the game very difficult as their opponents showed little ambition.
"Our aim was clear. We played the ball around and we tried to attack. I do not think that it is fair that the only team that looks to go forward ends up with as many cards as the team that tries to break up play," he continued.
"[Michael] Ballack should clearly have been given a second [yellow card] because Iniesta was about to enter the area."
Lionel Messi was expected to be the star and hopes were high that he would pry open Chelsea's back four, but Guardiola was quick to defend the Argentine even though he did not score.
"Messi never plays badly. At half-time we spoke about him producing a bit more. But when a team is so tight at the back it is not easy for the forwards and even more difficult when the opposition are physical," he added.
"We will come back though and look to play how we know we can.
"With five or six players sitting back, and more most of the time, and with some physically strong players, we still wanted to go forward.
"We created chances and gave a good account of ourselves, but football is always difficult when one team does not want to play.
"While I am coach of this team we will go out and attack in every game.
"I do not know if we will lift a cup in the end, but I can assure you that we will go on holiday without any regrets and without people saying we should have any."
