Glenn Murray scored his 100th league goal for Brighton as they delivered a Knockaert blow against their rivals Crystal Palace at Selhurst Park.

James Tomkins misjudged the flight of Lewis Dunk's raking ball as Murray fired Brighton into the lead on a windswept day in south London.

Luka Milivojevic converted a penalty shortly after half time to level the scores, but it was Anthony Knockaert's stunning strike with 15 minutes remaining which settled the tie.

Here are five things we learned...

Two stunning strikes made the difference

One better than the other.

Murray took it first time and volleyed the shot past goalkeeper Vicente Guaita into the far corner of the net, not least from a fairly tight and difficult angle.

Then Knockaert cut inside from wide to evade Patrick van Aanholt, clipping the post as he struck from the edge of the penalty area. Not sure Guaita knew much about either goal.

Harsh to see Tomkins' mistake as anything but misfortune

You can see what he was trying to do, and most times it works. It's just on this occasion it didn't work and he was subsequently punished by a rather clinical finisher.

The wind was particularly strong and probably did play a significant role in the goal as Dunk's pass glided all the way through to the heart of the Palace defence.

It was a bizarre moment in an otherwise fine performance for Tomkins, he learned from it and hardly put a foot wrong thereafter.

Palace were poor, but give credit to Brighton

The visitors' defending was superb throughout, with defenders intervening at the right time to deny Palace's lightning quick attack from having any real advantage.

Lewis Dunk and Shane Duffy both had moments where they got their bodies in the way of shots from the attacking trio on what must have been a very frustrating day.

Had Davy Proepper not brought Andros Townsend down in the box then one wonders whether Palace would have scored that day.

Was Knockaert lucky to not be sent off?

It only took a matter of seconds for the derby game to spring into life, when Milivojevic was left writhing in pain on the floor.

Replays suggested he was a little fortunate to just get a yellow card - his foot was left in a sensitive area in between the captain's legs.

Hard to suggest it was malicious but, all the same, it was pretty poor.

Should Brighton have had a penalty?

Later on, it was Brighton's turn to feel aggrieved when Scott Dann wad adjudged to have pulled down Shane Duffy in the box during a set-piece.

Duffy pleaded his case as play continued but replays, again, suggest there was a touch of fortune for one side - and had referee Craig Pawson spotted it he may have awarded a penalty.
