The EFL's official round-up records Leeds eliminating Nottingham Forest and Brentford scoring six on the opening night of the Carabao Cup second round. The results matter, but the competition also provides an early test of squad depth and tactical adaptability.

For Leeds, the useful signal is the ability to make a knockout match uncomfortable for Premier League opposition. Cup ties compress the margin for error: one aggressive spell, one set piece or one substitution can outweigh long periods of possession.

Brentford's six-goal output points to another question. Can the same attacking connections survive when the opponent is stronger and the game offers less transition space? A cup rout is evidence of execution, not proof that every league problem is solved.

The next round should be read in the same way. Rotation is not a reason to dismiss the matches; it is the point. The competition reveals which coaches can change structure without losing intensity.
