Arsenal defender Laurent Koscielny says they take great confidence from their unbeaten tour of the Far East.

The Gunners won all four of their tour games.

Koscielny said: "We won all our games so that's good for confidence. We had a lot of training and all the players trained very well and gave themselves for the team.

"Pre-season is very important for the Premier League. It's a long season so we need to be fit - I think we did well."
