Deila explained that he feels his team were sloppy in the final 30 minutes of the win against Ross County over the weekend, as the club got their Scottish Premiership defence off to a good start.
He’s suggested the poor performance from the team in the closing stages of the match was a result of the game coming so shortly after the first leg of the Champions League qualification game against Qarabag.
“Always you want to play better and today I felt for 60-65 minutes it was an okay performance. But the last 30 it was sloppy and messy,” he told the Glasgow Evening Times.
“We were not together as a team and we lost the ball all over the pitch which was a little bit disappointing.”
“But, also it’s two and a half days since we played the last game and it was a big match with a lot of intensity. You can see also that some of the players got a little bit tired. There were going to be a lot of changes.”
A common problem for the season
Deila’s comments are evidence of a common problem that Celtic are just going to have to deal with over the course of a long season.
They are one of the biggest British clubs around and as a result, have a strength which allows them to compete in multiple competitions.
That means a high ratio of games and also means that the manager needs to stay firmly on top of making plenty of changes to keep everyone in the squad fresh and effective.
