The Blues made it back-to-back 3-0 wins over the Gunners in the space of five days with a devastating display of attacking football at the Emirates and the boss couldn’t have been happier.
“Mentally we were strong,” said Pep. “We were clinical. We scored three outstanding goals. After that it was not easy - the first 15 minutes of the second half we were poor. Still, it's an amazing result for us and we made another step forward.
"It’s so difficult to win two games in a row against a team like Arsenal, and we did it in tough conditions.
“It was so important to win again. We want to be champions and every game we win we go nearer.
"They were all nice goals tonight and Ederson was outstanding, saving the penalty, because the game was not won.
“Arsenal can create chances from nothing in 10 or 15 minutes and the way we started the second half was not good, but it’s difficult to stay focused after winning a trophy four days ago.
"We created enough chances to score. I think it was three shots to score three. They arrived at the bye-line one or two times so Arsenal had chances, but we did our job.
“That was important because we have tough fixtures coming up, Chelsea, Everton, United and Tottenham. It was important to keep 16 points in front and improve the goal difference.
"We are out of the FA Cup and we won the League Cup. Now it's just two competitions and you fight for one of them for 10 months. These are the last steps to be champions, you keep going until the end.
"We have to win five games. We don't think too much. Now we play Chelsea. Hopefully we have the desire to win, to be the best team in England. We forget that we are tired."
