West Brom are out of the League Cup after they lost 2-1 at home to Millwall last night.

Boss Slaven Bilic made nine changes for the game, although Neil Harris rotated heavily as well, with the cup fixture coming just days after the sides drew in the league.

That proves the priority for both is the Championship, although Bilic will still be annoyed at the manner of the defeat considering Albion took the lead through new signing Charlie Austin.

With the Baggies back in action at Luton this weekend, it will have given the boss food for thought and here we look at THREE things we learnt about Albion last night...

Charlie Austin will score goals

Arguably the main positive for the Black Country side was the goal from Austin.

The striker was brought in from Southampton to replace Dwight Gayle and whilst he scored a straightforward goal last night, it shows he will be in the right position at the right time.

He had more chances too and that will encourage Bilic that Austin will thrive in the first-team.

Defending set-plays is a problem

The Lions two goals last night came from corners and the defending just wasn't good enough from Bilic's side.

The Championship is a strong league and if they can't fix those issues pretty quickly then it won't really matter how much they dominate play, because conceding cheap goals will cost them games.

Those on the fringes didn't impress

Having made nine changes last night, Bilic will have wanted to see a big performance from those on the fringes as they look to push for a spot in the XI.

However, whilst a few made a case to start at Kenilworth Road this weekend, such as Austin, on the whole, it was a disappointing display.

So, you can't expect many of those to feature against Luton.
