Arsenal are beginning to show the form and style of champions in the Premier League and they have another opportunity to demonstrate that against Middlesbrough. Aitor Karanka's side have struggled in recent weeks but present a potential banana skin for Arsene Wenger's side.
Elsewhere, Leicester City have not been able to put together the same sort of results as they did last season while charging to the Premier League title. A 3-0 defeat against Chelsea has left them in the bottom half. They will be hoping to turn around their form against Crystal Palace at the King Power.
