The Blues slipped to a fourth defeat in six league outings in Sunday’s 3-1 home reverse at the hands of Manchester City, who scored all their goals inside the opening 35 minutes.
“We’re in a tough period, it’s going to happen to everyone at times and we’ve been in these situations ourselves before,” said Pulisic.
“We have a game next week where we need to start turning it around because we do need to start getting results quickly.
“We’ll watch this game back, look at it as a team and see what we can improve on.
“It’s not going to be easy but we need to show character now.
“We have some games coming up where we need to turn it around quickly and start putting together a run of results.”
Callum Hudson-Odoi bagged a late consolation but the damage had already been done before the break, as Pulisic admitted.
“We conceded goals with a lot of counter situations and we weren’t prepared to stop that so the first half really let us down,” Pulisic told Chelsea‘s website.
“They were able to beat us on some transitions where we needed to defend better and be a little smarter and then we allowed them to dictate the tempo of the game.”
