(Reuters) - Celtic manager Ronny Deila will leave at the end of the season despite almost certainly leading them to the Scottish Premier League title, the club said on Wednesday.

Norwegian Deila secured a league and cup double last year in his first season in charge and they are eight points clear of Aberdeen with five games to play.
