Arsene Wenger admits Granit Xhaka must address a problem with his tackling technique but fears the Swiss international has become a victim of his bad reputation.
Xhaka has been booked in each of five appearances since he was sent off against Burnley, in January, his third red card of the season for club and country.
The Arsenal manager believes the 24-year-old midfielder is a 'fair player' who is booked by referees when others escape.
'He is in a position where on the first foul he gets a yellow card,' said Arsenal boss Wenger.
