€120m signing Enzo Fernandez made his Chelsea debut but could not help his new side claim only their second win of 2023 as they were held by Fulham at Stamford Bridge.
Argentina midfielder Fernandez completed a £107m move to the Blues from Benfica three days ago and Graham Potter opted to hand him an immediate start.
He made a solid impression and almost enjoyed a dream debut when his curled effort flew just wide of the post in the second half.
Kai Havertz also went close before the break when his lobbed effort from Hakim Ziyech's superb pass clipped the woodwork before the ball was cleared off the line, while debutant David Datro Fofana had a shot cleared off the line late on after showing great control to wrongfoot the goalkeeper.
But overall Chelsea did not do enough to earn the win as they again struggled to create real goalscoring chances, finishing the game with just three shots on target.
Fulham fully deserved the point after a superb defensive display and move up to sixth in the table, three places and two points above Chelsea.
Blues manager Graham Potter later said: "There was a lot of excitement and positivity from the start, a good atmosphere. The spirit of the players was really good. They worked hard for each other against an organised team.
"They've been together a while. We're a different stage of that – players coming back from injury and new players. We needed time to settle everything down. We were missing the connection, fluidity and confidence that comes from knowing each other.
"The decision we took in the window you can see the profile in terms of age. We feel we have a very strong group of players. We have to gel and become a really good team. That's where the work is.
"It's working together. When players have been injured they have not been on the training pitch. We have new players with us. It's about getting ideas across and woring with the group.
"Sometimes you have to look at the whole package. Young players, nice mix of them both. For us it's about improving.
"New players are adapting to a new country and a new league. It's not straightforward. When the price tag is what it is questions will be asked, it's the nature of the business."
