The Frenchman turned in a stunning performance in Palace's 3-1 win against Brentford, earning a 9.3 player rating.
Olise scored twice for the Eagles in a superb offensive display, also providing two key passes and completing five of his six attempted dribbles.
His second goal particularly stood out, receiving the ball on the edge of the area and darting into the box before slotting an effort in the bottom corner.
Palace next find themselves in FA Cup action, hosting Everton on Thursday evening.
