Pedro opened the floodgates for the recently crowned Club World Cup champions with a 12th minute penalty before the likes of Andres Iniesta , Thiago Alcantara, Xavi, Cristian Tello, Isaac Cuenca all registered their names onto the score sheet to send the minnows packing from the Nou Camp.
"If we've won prestige it's because of demonstrations like today's," Guardiola purred to the club's official website.
Having recently returned from a grueling trip from Japan after the Club World Cup exploits, Guardiola revealed that he was left in awe by his charges' "capacity to play the round of 32 in the King's Cup after being named the best club in the world."
"The way they behave is admirable," Guardiola added.
"We studied images [of Hospitalet] that we'd usually skip, the players can't perceive that we don't do our job and then demand that they do theirs."
Guardiola also paid tribute to the Barca faithful for their continued support.
"It's great that they came and cheered us on. The stadium wasn't full but we heard the 50,000 people, I'm very thankful," he said.
The former Barcelona midfield maestro also lavished praise on starlet Isaac Cuenca.
"He's been impeccable all year. We hope that with humility, the behaviour of being seen and talking little, that he will be ready and as a player, be at the required level," Guardiola added.
Barcelona will end 2011 in second place in the La Liga standings, three behind arch rivals Real Madrid as they embark on their traditional winter break.
