Celtic: Ronny Deila's ups and downs in Glasgow

Celtic and manager Ronny Deila have announced that they are to part at the end of the season.

The 40-year-old Deila arrived in June 2014 having won the Norwegian championship with Stromsgodset in his homeland.

In his first season, he led Celtic to a fourth consecutive league title and lifted the Scottish League Cup with a 2-0 victory over Dundee United.

A second title under Deila seems certain as they lead the Scottish Premiership by eight points from Aberdeen.

But they failed to reach the Champions League group stage in both seasons and, this term, finished bottom of their Europa League group and were knocked out in the semi-finals of both domestic cup competitions.
