Crystal Palace boss Pierre Sage has been speaking to the media before Sunday's Premier League game against Brighton at Amex Stadium (kick-off 14:00 BST).

Here are the key lines from his news conference:

• Sage "doesn't know" if Dean Henderson is available to play and will decide after training later on Friday.

• When asked if Jean-Philippe Mateta, Ben Chilwell or Takehiro Tomiyasu have a chance to return, the Palace boss responded: "Potentially. I said the same thing one or two games ago and it wasn't the case. I prefer to wait. At the moment, we hope, we expect, but we don't know."

• On Thursday's Europa League defeat by Lyon: "The bad result was a consequence of the first half. We didn't play and gave all the initiative to Lyon. I was frustrated because we reacted positively [in the second half] but too late."

• On the rivalry between Palace and Brighton: "I know the fans don't like this name [the M23 derby] because it is too far to name it this. We know it is a big game for the club and the fans, and we have to show our better phases, like the second halves of our last two games."

• He added: "On the first day I came here, the first thing they told me was that. In the last few days I've read a lot of articles about the rivalry to understand why. When you have something special, you have to do a special game."

• When asked if the Eagles are being left out of the 'Bermuda triangle' name given to Brighton, Brentford and Bournemouth: "We don't have to analyse that now, we don't speak about that. The club won titles with this strategy and we have to be confident in the board and how they choose and keep players. It's our identity."

• Comparing Ligue 1 and the Premier League, Sage said England's "average level is higher" and "every game is difficult."
