Chelsea boss Frank Lampard has thrown down the gauntlet to Tammy Abraham.

Lampard says the young striker knows how he'll be judged.

"It's normal that the top strikers are judged on goals, and the next level of that is: do you score goals against the big teams," said Lampard. "I understand that because against someone like [Virgil] Van Dijk, a defence like Liverpool, a team like Liverpool, maybe it's harder to create chances.

"So it's what can you do individually to try and create them, and how clinical can you be after that. He's shown great signs this season but it will be another test on the way and it's not the be all and end all day and we make our judgements after this. But for the top strikers like Didier, we all remember the amount of times he scored in finals and semi-finals and really important games and I think, quite rightly, players are judged on that

"The thing I love about Tammy is his enthusiasm. He takes every day like it's a challenge and a happy challenge. He wants to come in with a smile on his face and wants to score goals in training and be the best he can be. I think if you've got that attitude, you've got a great chance, because we know he has the talent."
