Rafa Benitez has big calls to make in the midfield and up front as Newcastle head to Stamford Bridge.
Newcastle United stopped the rot at West Bromwich Albion on Tuesday night, fighting back from two goals down to claim a point and end a four-game losing run.
There were some impressive performers in that Hawthorns comeback, but the magnitude of the stage for this next clash might well mean some still miss out...
Karl Darlow came into the side as Rob Elliot belatedly lost his place, with the former doing little wrong at West Brom.
DeAndre Yedlin disappointed but there are few alternatives, while Chancel Mbemba perhaps did enough to prolong Paul Dummett's wait for a return on the other side. Florian Lejeune and Ciaran Clark are established starters in Jamaal Lascelles' absence.
One of the two big calls is in the middle of the field, from where Jonjo Shelvey turned Tuesday's game after arriving from the bench.
He and Mikel Merino both prefer to attack - unlike Isaac Hayden and his defensive-minded game - but Benitez trusted the pair against Liverpool earlier in the season and he may feel they have done enough to earn a start.
Matt Ritchie and Jacob Murphy will surely continue out wide, with Ayoze Perez through the middle, but there is also a decision to be made at the head of the line-up.
Aleksandar Mitrovic was instrumental in Newcastle's fine end to their last match and, having emerged from the bench ahead of Dwight Gayle, it might just be that Benitez will finally trust the Serb to lead the line in place of Joselu.
