Ronny Deila disappointed despite Celtic win

Celtic manager Ronny Deila has admitted that his side put in a 'mixed performance' during their win over Ross County in the Scottish Premiership.

The Hoops started their title defence with a 2-0 victory on Saturday as Leigh Griffiths and Stefan Johansen got the goals at Celtic Park.

However, Deila conceded after the game that his players struggled for consistency over the 90 minutes.

"You always want to play better," he told the club's official website. "Today for 55-60 minutes we put in an okay performance. The last 30 was sloppy and messy. We wren't together as a team and lost the ball all over the pitch. It was a little disappointing."

Celtic are back in action on Wednesday when they travel to Azerbaijan to face Qarabag FK for the second leg of their Champions League third-round qualifier. The Scots earned a narrow 1-0 win in the opening leg.
