Good evening and welcome to Eurosport's LIIVE text coverage of Chelsea's EFL Cup quarter-final at Brentford. Stay with us here for all the updates, with kick off at 19:45 GMT.

Barkley is to the right, and Kovacic is to the left as the visitors dominate the early possession. A ball forwards from Azpiicueta finds his opposing compatriot Fernandez in the home penalty area, but Chelsea recover his long kick and rebuild down the left through Alonso and Kovacic.

Barkley and Kovacic are a little more advanced in the engine room for the away side, with Saul Niguez the deepest-lying of the midfield three. It's definitely more of a 3-5-2 for the European champions as they match their hosts up.

It is Xavier Simons on the right flank for the Blues with Jude Soonsup-Bell leading the line with Harvey Vale.

And the atmosphere builds.

And the stage is set.

Brentford: Thomspon, Norgaard, Forss, Ghoddos, Onyeka, Toney, Peart-Harris, Stevens, Cox.

Chelsea: Rudiger, Jorginho, Kante, Pulisic, Bettinelli, Mount, James, Webster, Hall.
