Koscielny, who will play in Saturdayâ€™s quarter-final in place of the suspended Philippe Mexes, has opened up over the conflict in the squad.
â€śThings were said in the changing room,â€ť said Koscielny. â€śThey were said but that will stay between us.
â€śThere were some things to say and everyoneâ€™s aware of that. But these things happen.
â€śNow we have to turn the page. But we were unbeaten in 23 games so I donâ€™t see why we should throw all that away.
â€śWe were below par on every level against Sweden. When we got back to the dressing room we knew we hadnâ€™t done what we had to do and some things were said.
â€śMaybe we did ease up a bit subconsciously. We have to work hard over the next three days to put that right.â€ť
