Arsenal defender Laurent Koscielny insists they're capable of a big second-half of the season.

Arsenal need a top-four finish to ensure another crack at club football's blue riband trophy - or to win the Champions League this year.

Koscielny said: "Arsenal are one of the biggest clubs in the world and it is 17 years running that we've qualified for the Champions League.

"I don't want to be the first one not to qualify for the Champions League so we are all determined do our jobs to be in the draw for next season.

"We will give everything we can do to get there."
