City have been ahead of the Reds in each of the previous derbies the Catalan has overseen, but United have a one-point advantage going into this clash.
“It’s an ask for Man United, not for us or myself,” said Pep.
“The Previous season is the previous season. In previous seasons we did it better, that’s true. But why? That’s a question for Man United.
“Every derby is interesting and nice. Being in front or not in front. It’s always a little bit special, of course, but you have to be focused on the game.”
Pep also admitted United’s pace was a threat to a City defence that has kept five clean sheets in a row…
“Yes of course it’s difficult (to defend against),” he said.
“All big clubs have incredible players up front.
“We have to try to punish them.
“They know we got to Old Trafford trying to win.
“We cannot deny they are exceptional club and team.
“We knew it when I was at Barcelona and we faced them in the Champions League.
“Knew it when I arrived.
“I cannot say since I arrived they do not have a good squad, they have.”
