opener.
The Frenchman's superb scissor kick put away a Mesut Ozil cross but the lead lasted 12 minutes until Joel
Ward's driven shot drew Palace level.
Connor Wickham hit the post on his home debut before Damian Delaney sliced a Sanchez header into his
own net.
Jordon Mutch almost inadvertently grabbed a late equaliser when the ball struck his head and went over
from a corner, while Petr Cech held a Ward header in a frantic finish.
But despite Palace's combative display, Arsene Wenger's side ultimately deserved the three points for the
quality of their movement and resilience in defence.
