Arsenal boss Arsene Wenger is upset with Alexis Sanchez.

For victory at Hull City, the Chilean forward ignored the Gunners' agreed penalty taking order, only to see his spot-kick saved by Tigers' keeper Eldin Jakupovic.

The Mirror says Wenger has warned the star about his future conduct.

Following last week's incident, the veteran gaffer has been forced to confirm again that Santi Cazorla will be his first choice taker if his team are awarded a penalty against Chelsea today.

The former Malaga ace had scored a last minute penalty in the previous week's 2-1 victory over Southampton and was said to be shocked by his team-mate's move to usurp him at the KCOM Stadium.
