Chelsea will be without a handful of their first-team stars for the Champions League clash against Ajax.
N’Golo Kante, Antonio Rudiger, Andreas Christensen and Ross Barkley were the most notable absentees as the Blues touched down in Amsterdam.
Barkley is unavailable after he picked up an ankle injury during the 1-0 win over Newcastle on Saturday.
Kante remains out of action after he injured his groin while on international duty with France.
And Christensen, who has made seven appearances in all competitions this season, has been ruled out.
The defender is expected to spend the next two weeks on the sidelines with a hamstring issue.
All three of the players missed Chelsea’s Tuesday morning training session at Cobham.
Rudiger was spotted with his team-mates at training, but did not make the trip to the Dutch capital.
Lampard has picked a 19-man squad to travel to the Netherlands for the group stage clash at the Johan Cruyff Arena.
