The teenage wing-back Lewis Hall, who started at Manchester City in the Carabao Cup on Wednesday, makes his Premier League debut for Chelsea. He replaces Marc Cucurella in one of six changes from Chelsea’s last league game, the 1-0 defeat to Arsenal. Raheem Sterling isn’t even in the squad, though we don’t yet know why.
Callum Wilson is only fit enough to be on the bench for Newcastle. Chris Wood replaces him in one of two changes from last weekend’s 4-1 win at Southampton. The other is Joelinton for Jacob Murphy.
