Gallagher, who has come off the bench in our two previous Premier League fixtures this season, starts for the Blues for the first time at Elland Road, replacing the injured N'Golo Kante in midfield alongside Jorginho, who captains the team.

Elsewhere it is an unchanged side from Tuchel following our 2-2 draw with Tottenham Hotspur last week, meaning Edouard Mendy continues in goal behind a back three of Reece James, Thiago Silva and Kalidou Koulibaly.

Ruben Loftus-Cheek looks set to be at wing-back on the right side, with summer signing Marc Cucurella on the left. It is an unchanged attack for the third game running, with Mason Mount, Raheem Sterling and Kai Havertz forming a front three.

There could be another debut at Elland Road, as Carney Chukwuemeka is named among the substitutes for the first time since joining from Aston Villa, while Ethan Ampadu is on the bench for the first time since our Europa League final win over Arsenal in 2019.

Leeds also make one change to the team which drew 2-2 with Southampton last time out, as Daniel James replaces injured former Chelsea Academy striker Patrick Bamford up front.
