Arsenal need to be tougher at home, says Koscielny

Arsenal trail leaders Chelsea by five points in the table and that is partly down to the fact that they have struggled to kill off teams at home.

Laurent Koscielny has challenged his Arsenal team-mates to become "unbreakable" at the Emirates Stadium.

Arsenal, who take on Newcastle United at home today, trail leaders Chelsea by five points in the table, and that is partly down to the fact that they have struggled to kill off teams at home.

Laboured wins over Birmingham City and bottom club West Ham United followed the shock defeat by West Bromwich Ablion.

Summer signing Koscielny, the centre-back, said: "The toughest match for me so far was definitely West Brom. To lose at against them at the Emirates left a bitter taste and we have to be unbreakable at home."
