Mikel Arteta paid tribute to brilliant Bukayo Saka who sent Arsenal eight points clear of Manchester City heading into the international break.
The England winger scored two and made another to destroy Palace as the Gunners racked up their 22nd League win of the campaign - as many as they managed in the whole of last season. Arsenal also now have their most ever wins after 28 matches.
Arteta said: “We have individuals that excel to be at the level that we want. Bukayo was again really good. Really affecting the game with his contribution, especially in the opponent's box. So yes, I'm really happy with him."
