Arsenal have offered Chile international Alexis Sanchez a new contract worth £300,000 per week, to make him the Premier League's highest paid player.

Alexandre Lacazette and Sead Kolasinac may make their league debuts for Arsenal, but Alexis Sanchez is ruled out with an abdominal strain. Laurent Koscielny is banned, while Per Mertesacker, Mesut Ozil, Jack Wilshere and Aaron Ramsey are fitness doubts.

Leicester midfielders Danny Drinkwater and Vicente Iborra are unavailable because of muscle problems. Defender Robert Huth is recovering from ankle surgery. Kelechi Iheanacho could also make his debut, although the former Manchester City striker may struggle to last 90 minutes, while winger Riyad Mahrez should be involved despite being a transfer target for Roma
