Frank Lampard admitted he wants to sign a new striker after Newcastle damaged Chelsea's bid for a top-four finish in the Premier League with a dramatic 1-0 win at St James' Park on Saturday.
With Tottenham held by Watford earlier in the day and Manchester United facing runaway leaders Liverpool on Sunday, Chelsea would have cemented their grip on fourth place with a win on Tyneside.
But Lampard's side were unable to muster the cutting edge required to break down stubborn Newcastle and fell to Isaac Hayden's header with just 20 seconds left in stoppage-time.
Chelsea's first defeat in four league matches leaves them five points clear of fifth-placed United and Lampard is growing tired of his team's struggles against defensive opponents.
"We know we have problems at the top of the pitch in terms of we don't get enough goals. If you don't score you are always liable for a sucker punch and they got it," Lampard said.
"If we are looking for people to bring in to the areas to win games when you are controlling it, it is scoring goals.
"We can't work anymore in training on finishing. You need to have that killer instinct in front of goal. We need to score more goals from front-line areas if we are going to get to where we want to be.
"It's quite clear from what I am saying now that we know where we need to strengthen but we shall see."
"We have had more possession than any of our opponents in every game this season. It is a sign we have a lot of the ball but we are not scoring enough."
