Chelsea manager Frank Lampard has confirmed that striker Tammy Abraham will not feature in Saturday's meeting with West Ham because of the injury he picked up against Valencia.

Abraham was left in immense pain on Wednesday evening after landing on the feet of centre-back Ezequiel Garay, but he did admit after the game that his hip ​felt much better soon after he was stretchered off.

However, speaking in his pre-match press conference (via ​Goal), Lampard revealed that Abraham had not recovered in time for the game, but he refused to speak about who would replace him.

“We will know by the end of the weekend, he won’t be available for tomorrow," Lampard confessed. "There’s a lot of pain.

“We will see by Monday. It is a squad game, the lads have been training well and when opportunities come they are ready.”

​Michy Batshuayi has operated as Abraham's backup this season, but Lampard also has the unsettled ​Olivier Giroud at his disposal. When asked specifically whether Batshuayi would start, Lampard cryptically responded: "We’ll see."

However, he was full of praise for the Belgian, adding: “[Batshuayi brings] a work ethic, a quality. It is not easy when you are not playing as many minutes as you want. I have seen a great work ethic and his quality. It is great to see.”

While this attacking issue will be high on his agenda, Lampard must also work to steady his defence. ​Chelsea have kept just one clean sheet in their last seven games and looked vulnerable at times against Valencia.

“I didn’t like the last 20 minutes against Valencia, but I’m not concerned about defence," he insisted.  “We have conceded more than we want. In the ​Premier League you are going to concede goals, there is always need for improvement. We are okay, but we want more.”

Lampard remains unable to turn to centre-back ​Antonio Rüdiger, who has been out with a groin injury. He added: “He is getting closer, it is a mini pre-season, he is working very hard.”
