For the second game in a row Christian Pulisic was left on the bench for Chelsea whilst N'Golo Kante and Conor Gallagher lined up in the unorthodox, high-pressing and largely confusing attacking system of Frank Lampard. Just like against Real Madrid, it didn't work.
Although the Blues were able to carry out part one of their game plan in the Champions League second leg they failed to score. Against Brentford they didn't do either and more questions were asked of Lampard's tactical choices.
On the substitutes bench available to him were Mykhailo Mudryk, Pierre-Emerick Aubameyang, Joao Felix, Hakim Ziyech, Noni Madueke and Pulisic. The first two got the nod at half time but failed to make a breakthrough before the Bees added a second. Madueke was introduced shortly after.
