The news was expected following the Hoops’ disappointing penalty shootout defeat to Rangers in the Scottish Cup semi-final on Sunday.
And it’s now been confirmed by the club that he’ll walk away from Parkhead in the summer.
A statement on celticfc.net reads: “Celtic Football Club today announced that Celtic manager Ronny Deila has decided to leave the club at the end of the season. Ronny has already led Celtic to a League and Cup double last season and is currently aiming to deliver Celtic’s fifth consecutive Premiership title.”
Deila was also quoted too, recognising that as well as having some success in his time at the club, there were also disappointments.
The Norwegian said: “There have been some disappointments and times when we have not achieved what we had hoped for and I’m realistic and honest enough to admit that, but I know that the players, myself and my backroom team have always given everything we had to bring success to our supporters.”
Here’s the immediate reaction from fans:
When Deila leaves it will be at the end of his second full season with the club after replacing Neil Lennon in 2014.
The Hoops boss led the club to the League Cup and league title in his first season, but failed to make any real impact in Europe over his tenure and that’s where a lot of the criticism of the job he’s done has came from.
Sunday’s defeat to Rangers means Celtic can only play for the league title now this season – something Deila will be hoping to lead them to in the remaining fives games.
Celtic fans – what would you say to Deila as he gets set to leave Glasgow?
