For all City’s overall excellence in the 2-1 victory, the hosts managed to make it an edgy finish in the closing stages of what had otherwise been an exemplary display by the champions.
“We had the chances to kill the game and score a third and then maybe a fourth, but we missed them,” said Pep.
“It is what it is. We knew it. We are not new in this league and we know it happens.
“In the first half they had one clear chance, but we had many. We had three or four more chances after we went 2-0 ahead when the game was under control.
“Then, okay, we start to lose balls and let them have the opportunity to come back into it.
“And of course, when they scored with 10 minutes or so to go, you suffer.
"We didn’t score the third, they made it 2-1 and in the last minutes anything can happen.
“In this league, you have to score the third goal and we didn’t do that, that’s why we suffered near the end.”
Despite the late Hornets rally, the Catalan was keen to highlight what had gone before the Watford goal and frantic last moments.
“We make a good performance," he said.
"The game was really good, we were so aggressive, and we won a lot of balls.
“Foster made some incredible saves. After that we forget to be in the position and our build up was not as quick as normal and the chances we had to counter-attack, we missed.
“Now we try to recover our legs and minds and go to Chelsea on Saturday and play our game.
“We know how difficult it is at Stamford Bridge, but first, we must rest and recover.”
