The Gunners snatched a late 2-1 win against West Ham United on Saturday to make it back-to-back victories in the Premier League.
Mikel Arteta's side also beat Liverpool on penalties in the Community Shield last month - the second piece of silverware Mikel Arteta has lifted in nine months at the club.
Ahead of Wednesday's trip to the King Power Stadium, Sports Mole looks at how Arsenal could line up.
With a trip to champions Liverpool to come next weekend, Arteta is expected to make mass changes to his starting lineup for Wednesday's cup tie.
Eddie Nketiah is one of those who is likely to profit from the rotation, having scored Arsenal's late winner against West Ham at the weekend.
Mesut Ozil is another possible option for Arteta, but the German playmaker has not been included in the squad so far this season and that is unlikely to change here.
With four defenders still nursing injuries, David Luiz may have to return to the starting lineup sooner than Arteta perhaps would have liked.
