Signed from Real Madrid in a club record transfer, Alvaro Morata was handed his full Premier League debut on Sunday afternoon.
The Blues visited rivals Tottenham Hotspur at Wembley, looking to bounce back from their shock opening day defeat to Burnley.
Morata had a golden opportunity to give Chelsea the lead within five minutes but somehow managed to place his header wide of the post.
Michy Batshuayi was relegated to the bench after the 24-year-old Spanish international scored after coming off the bench against Burnley last week.
His manager Antonio Conte looked far from impressed after an unmarked Morata headed off target.
Last season's top scorer Diego Costa remains in Brazil after refusing to return to train with the Chelsea reserve team.
The 28-year-old Spaniard has seen his relationship with Conte completely break down after the Italian coach told him he was no longer in his plans by text over the summer.
Costa scored 20 Premier League goals last season and surely would've found the back of the net from six yards.

Morata was quickly trending on Twitter, with Premier League fans enjoying the miss almost as much as his penalty miss against Arsenal in the Community Shield.
Some Chelsea fans were quick to jump to Morata's defence, backing him to find his feet in a Chelsea shirt.
Ahead of the London derby, Morata spoke of his extra motivation following his less-than-impressive recent Wembley outing.
"It is a big motivation for me, [Wembley] is a bad place for me at the moment because I missed a penalty," Morata told Sky Sports this week.
"But I have the opportunity to take this feeling out of my body, my head and all the heads of Chelsea supporters.
"I am very motivated for this game, it is against Tottenham, a very big team."
