Frank Lampard says Chelsea need to stick by Timo Werner.
The German missed a penalty in Sunday's FA Cup win over Luton Town.
Werner has not scored since early November, but Lampard is confident things will turn around for his star attacker.
"With Timo I'm disappointed for him. He gave a lot to the performance today. He was a threat behind, his link up with Tammy, his link up with people around him, it's just one of those things," Lampard said.
"When it's not going for you quite, it can happen. I missed penalties, I know the feeling. I know he will feel despondent, maybe now and the last few minutes of the game, but he shouldn't be.
"It's my job and his teammates' job to lift him and he will be fine. It was almost a sign of what's going on for Timo at the minute, it's not quite dropping for him, but there will be a time when he takes penalties without thinking about it and hits the back of the net without thinking about it. At the moment that's not quite the time for Timo, but it will come and hopefully soon."
