There is one change to the team that started the win at Norwich a week ago.
Fikayo Tomori comes in for Andreas Christensen to make his second Chelsea league appearance. The previous was back in May 2016 when he was used as a substitute against Leicester at the Bridge. The 21-year-old defender knows today’s opponents well of course, having played them twice in the Championship last season when on loan at Derby.
Frank Lampard has explained his decision to make the change is due to competition for places and with Tomori training really well, he deserves his chance.With Pedro unavailable due to the hamstring strain he suffered in the warm-up last weekend, Mason Mount is expected to continue in a wider role with Ross Barkley more central. Tammy Abraham, the other goalscorer at Norwich continues up front.Eighteen-year-old Academy midfielder Billy Gilmour is on the bench.Sheffield United also make one change from their previous Premier League game. Oliver McBurnie comes in for David McGoldrick in attack.
Chelsea: Kepa; Azpilicueta (c), Tomori, Zouma, Emerson; Jorginho, Kovacic; Pulisic, Barkley, Mount; Abraham.
