One hundred and five days since he last handed in a team sheet, Frank Lampard makes four changes to his side.
There is one alteration to the defence that kept a clean sheet against Everton all that time ago. Andreas Christensen comes in for Kurt Zouma.
Mateo Kovacic starts, as do two fit-again players - N'Golo Kante and Ruben Loftus-Cheek. The latter is playing his first game this season. Jorginho remains suspended.
The attack is led by Olivier Giroud and with Willian and Mason Mount also selected, Pedro makes way.
Tammy Abraham is among nine permitted players on the bench on his return to Villa Park where he was so prolific on loan last season.
Explaining his striker selection before the game, Lampard said: ‘Oli finished really well before the break. He had a couple of small injuries at the start of this training period but it was just a choice today. It’s very important to let the players know that this is more than ever a squad game over this next period.
‘Certainly nobody should get their head down at not starting - we’re going to have to make subs and we’re going to need impact off the bench.’
Aston Villa are unchanged from their draw here against Sheffield United on Wednesday.
