Granit Xhaka could make his first appearance in a north London derby on Sunday - especially if Santi Cazorla doesn’t recover in time.
The Switzerland international scored against Ludogorets in midweek and is available to face Tottenham after serving a one-match suspension.
That came after a red card against Swansea City and Arsene Wenger will remind Granit - and all our players - to keep their discipline against Spurs.
"I have no specific idea what I will do [in terms of team selection] but am I bit concerned? Yes, of course," said the boss.
"Discipline is important because we want to be effective in all situations we face and in the derby it is important to keep control of your reaction and to have a strong discipline. It is part of the effectiveness in these games.
"Normally [Granit] is a very composed and calm guy, sometimes on the field he has a reaction that is a bit impulsive and he knows that. He has to work on that and keep control of his reactions in the game."
More polls to come later in the season!
