Arsenal football stars wear the Daily Mirror's anti-knife T-shirts as the club joins the Mirror's Stop Knives, Save Lives campaign.
Theo Walcott, Cesc Fabregas and captain William Gallas all threw their weight behind the appeal at Emirates Stadium.
In a heartfelt plea Gallas urged children to bring an end to knife culture that is blighting our streets.
The defender said: "Knives rob families and friends of precious young people. Give yourselves and others a chance to live together and be safe." Ben Kinsella, an Arsenal fan whose fatal stabbing prompted our campaign, was killed less than a mile away from the club's ground after a night out on June 29.
