Many see Olsson as a direct Mikel Arteta replacement. He is a very calm and graceful player, a very good all rounder, and he can easily dictate play when picking up the ball. One of the aspects the young Swede has notably picked up in his game is how to gain time on the ball.
Olsson was recognised by many Arsenal fans when he scored for Arsenal during their pre-season game against Boreham Wood. A through ball from Tomas Rosicky and Olsson finished off with a nice chip.
Olsson will be a great player one day.
