Frank Lampard has revealed that Chelsea will be without Tammy Abraham for a derby date with West Ham as the England striker is still in some considerable pain.

The Blues saw their in-form striker forced from the field during a Champions League clash with Valencia.

A blow to the hip left Abraham in agony and facing up to a spell on the sidelines.

He was quick to play down the severity of the knock after sitting out the second-half of a 2-2 draw at Mestalla, but will not be ready for Premier League duty on Saturday.

Lampard told reporters when asked for a fitness update on the 22-year-old: “We will know by the end of the weekend, he won’t be available for tomorrow. There’s 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.”
