We are at the end of a week in which we have had official confirmation that Ronny Deila will leave Celtic when the league campaign has reached its conclusion.

I think there are a number of different ways you can look at, but I would still say that the decision to appoint Deila in the first place was a good idea. He was seen as a progressive coach who had enjoyed success on a smaller scale and who came with a strong reputation for being able to build and develop a squad of players.

In many ways, the great disappointment of the way that it has not worked out is that there will now be a clamour for the tried and tested, for someone who is homegrown rather than an oversees manager who might do things differently, and I think that is a great shame.

We have a real tendency in this country to assume that one when foreign coach doesn’t work out that we have to steer clear of any similar venture in the future, and it is an odd way of thinking.

We will hear much over the coming weeks about a “Celtic man” getting the job and it is nonsense. What you need is someone who can come in and do a job; if they have no association with the club it really doesn’t matter.

But in a week in which we have seen managerial stock rise and fall, it is interesting to contrast Deila with the current bookmaker’s favourite for the post; David Moyes.

I am convinced that Deila will still be held in high esteem in Scandinavia, perhaps even more so because of his experience at Celtic. He is a young manager, he has his own ideas and his success in Norway with Stromsgodset coupled with the two years he has had at Celtic will still leave him in a good position to get another job.

He will still be a coveted manager in his homeland.

I have spoken to a lot of Celtic fans who seem excited by the prospect of Moyes taking over and yet, there will be people south of the border who will look at what Moyes has done in his previous two posts and feel that it has overshadowed a lot of the good work he done at Everton.

I do wonder just how much responsibility the players take on at Celtic for what has happened. I was commentating on the Molde game when Kris Commons lost his rag with the Celtic backbench and i did think at the time that it might have been the end of his Hoops career.

I know that he is a favourite with the fans but in many other clubs that might have been enough to have him shown the door.

But, I think we all knew that Deila was never the first choice for the Celtic job. I think he has conducted himself very well under trying circumstances these past few months and I do think he leaves with a lot of dignity.

He will go with potentially two league titles and a League Cup but his downfall has been the complete collapses that we have seen in the European arena. That is a little hard on him because he has not had the budget that other Celtic managers have enjoyed but I think we all appreciated that there was an inevitable change coming this season.

Mark Warburton was very clever with his comments in the aftermath of last Sunday’s Scottish Cup victory over Celtic.

He made an eloquent point about requiring money to strengthen and I think he is absolutely right. It is one thing to do it one a one-off but another entirely to sustain that over the course of the season.

Celtic have lost twice this season to Aberdeen, they have lost to Ross County, they have lost to Motherwell – Rangers are not the first domestic team to beat them. So while I wouldn’t rain on what was a fine achievement and a significant victory for the club, I would be reluctant to read too much into what it might mean for next season.
