The Bees came unstuck against the Seagulls, whose two first-half goals settled the contest.
More significantly, they missed the opportunity to leapfrog Liverpool in the Premier League table in the race for Europe.
Here is what Andrews had to say in his post-match press conference:

Performance
First half, we didn't hit the levels that we've been doing pretty consistently.
We're a little bit flat play with the same level of intensity that we have been doing really, really well.
And yeah, we certainly gave them a bit of a leg up in the first half.
Yeah, we're clearly disappointed. That's where the game was lost, obviously in the first half.
James Milner milestone
He's had a very special career.
The longevity of it, the professionalism obviously that he's shown throughout that period.
To still play at the level that he has is clearly really impressive.
Terrible timing (second goal)
It's the game. Injuries happen, substitutions happen.
The timing of it obviously wasn't good because it did give them a real leg up, going two-nil up.
Obviously very difficult to come back from that.
You've got to achieve something pretty special in the second half.
I think we're capable of that.
I think if we had have taken one of those opportunities, we could have made the last part of the game a lot more testing for them.
Unfortunately, we weren't able to do that.
Michael Kayode injury
The latest is he took a knock in training and we'll see how he is over the next coming week or so.
Half-time substitutions
Well, a lot.
We didn't play particularly well in the first half, so I wanted us to get back to what we've been doing really, really well in the last 10 games.
We've been the best team in the league.
That's a high bar. A really high bar.
And in the first half, we didn't replicate what has produced those levels of performances and fully deserved results.
So, going back to the previous question, we have a squad of really good players.
I feel like if some players aren't particularly performing to the levels, you try and change the dynamics within it to see can you get a reaction.
And it's not particularly down to the two players that came off.
It obviously could have been different players, but they were the ones that felt right.
Perspective to say nobody expected you to be in this position at start of season?
Yeah, I'm not really interested about the start of season.
We're here where we are now and I've been saying this pretty consistently behind the scenes that we are where we are because we've showed real bravery and courage to get to this point.
But before today we had 12 games left, now we've got 11, plus the cup exploits.
We need to keep pushing because that is a serious chunk of the season.
We need to be consistent in what we do.
We need to continue to show bravery and courage in everything we do.
And day to day, we need to keep pushing each other.
And today is a good full stop on that chapter because we'll learn from today.
We'll learn about what we could have and should have done a little bit better, the standards that we didn't hit.
And we'll go into that over the next couple of days and like I said, we'll continue to push.
