Enzo Maresca has made nine changes to his team for tonight's UEFA Conference League match against Shamrock Rovers, with the two new permanent additions to the senior squad both involved from the start.
Marc Cucurella and Noni Madueke are the only two players who started the weekend's Premier League win over Brentford who retain their place for this final league stage match in the Conference League, while Josh Acheampong and Tyrique George join them in the line-up after being added to the senior squad on a permanent basis this week.
Filip Jorgensen continues in goal in Europe, with Acheampong and Cucurella likely to be the full-backs ahead of him, while Renato Veiga and tonight's captain Axel Disasi complete the defence.
Cesare Casadei and Kiernan Dewsbury-Hall come into midfield, the former having served his one-game suspension in this competition.
In attack, George and Madueke look set to line up as the wingers, alongside Christopher Nkunku in supporting striker Marc Guiu.
It is a youthful bench, with five Academy players among our substitutes. Harrison Murray-Campbell would make his senior debut if he comes on.
Chelsea: Jorgensen; Acheampong, Disasi (c), Veiga, Cucurella; Casadei, Dewsbury-Hall; Madueke, Nkunku, George; Guiu
Substitutes: Bergstrom, Sanchez, Murray-Campbell, Tosin, Dyer, Rak-Sakyi, Joao Felix, Neto, Sancho, Vale, Mheuka
