Kai Havertz says the last few weeks have been "tough" for Chelsea after his header earned a narrow victory over Crystal Palace to ease the pressure on manager Graham Potter.
Havertz met Hakim Ziyech's cross shortly after the hour as the Blues ended a run of three successive defeats in all competitions.
"The last few weeks were tough. For everyone at the club, it is not easy under these circumstances," said the 23-year-old.
"A lot of things changed this year. We have so many injuries. Today we had five young players in the starting XI, they are doing a really good job at the moment.
