ATROMITOS v NEWCASTLE
Williamson and Dan Gosling are all expected to come in.
Newcastle take on Chelsea in the Premier League less than 48 hours after the final whistle in the Greek capital so Pardew will rest Yohan Cabaye, Demba Ba, Cheick Tiote, Jonas Gutierrez and Fabricio Coloccini.
Pardew insisted: “I won’t make 11 changes, but we have a lot of games coming up and it’s important that our best players have their energy levels up.
“I’m going to put out a team I think can win and that might not be all our big-hitters.
“Doing that would be impossible.”
