Chelsea will be without Hakim Ziyech and Callum Hudson-Odoi against Everton at Goodison Park this evening.
Both wingers have hamstring injuries and are expected to be out for two weeks.
Everton also have injury concerns – they are without James Rodriguez, Fabian Delph and Seamus Coleman.
James suffered a calf injury against Burnley, while Delph and Coleman have hamstring problems.
Christian Pulisic has also had hamstring issues but is in the Chelsea squad after training fully this week.
Speaking at a press conference on Thursday afternoon, Lampard confirmed that Pulisic is available despite having “a tiny bit of awareness” of his recent hamstring trouble.
Pulisic coming through that apparent scare is great news for Chelsea, who are unbeaten in 17 games.
The American recently returned to action, although he did not feature in this week’s Champions League game against FK Krasnodar
“With Christian it’s a work in progress,” Lampard added.
“I don’t want to call this an injury. Had the midweek game been a different type of game it may have been one where I would have used him.
“We know his abilities. He showed them when he came on against Leeds last week.
“I just have to find a way to get the best out of him regularly and consistently.”
Predicted Chelsea line-up:
Mendy
James
Chilwell
Silva
Zouma
Kante
Mount
Kovacic
Pulisic
Werner
Giroud
