Chelsea have had more possession of the ball than almost all the teams they’ve faced this season but goal scoring record have not matched the level of match domination.
The Blues were again dominant against a defensive Newcastle United on Saturday but loss the game thanks to a last gasp attack from Newcastle.
The Londoners had 19 shots but only four of those were goal threatening.
“If we are looking for people to bring in to the areas to win games when you are controlling it, it is scoring goals,” said Lampard.
“It’s clear from what I’m saying we know where we need to strengthen.”
With the game all but over in the 94th minutes, Isaac Hayden converted for Newcastle with the final attacking action of the game.
Lampard added: “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.
“We can’t work any more 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.”
Chelsea remain fourth on the log while Newcastle are 12th.
