Alex Oxlade-Chamberlain will be eager to impress against Blackburn.
Arsene Wenger may look to rest one or two key players with a tie against Bayern Munich looming just a few days later. One of the beneficiaries of this policy could be Alex Oxlade-Chamberlain.
This season, the English winger has struggled to emulate the impact he made in his first campaign with the club.
Things won't get any easier for him on Saturday when he comes up against Blackburn's Swedish full-back Martin Olsson.
Against most defenders, Oxlade-Chamberlain is able to rely on his explosive pace. However, Olsson is just as quick as Oxlade-Chamberlain, if not quicker.
The Arsenal man will need to use every trick he has at his disposal to get beyond the Blackburn defender.
