RONNY DEILA will tell his successor he has the players good enough to reach the Champions League - if the new man seeks his advice.

The Norwegian believes he leaves behind him a squad strong enough to qualify for the group stages, despite the failures of the past two seasons.

Deila will say his goodbye to the club on Sunday after the Ladbroke's Scottish Premiership trophy is paraded at Parkhead and then all attention will be on his replacement.

And he is confident that Celtic's European woes will come to an end next season.

Deila said: "I think this squad could get to the Champions League next year. You have to be ready and use the experience they have.

"The last two seasons we have been very close.

“We will meet the same kind of opponents next time and Celtic should be good enough to beat them seven times out of 10.

“Of course, I would be happy to take a call from the new manager. If he wants that, then it is not a problem for me. What would my advice be? I’ll leave that to the call.”

Deila’s popularity among the Celtic support on a personal level has always been positive and he is guaranteed a fantastic send off on Sunday afternoon.

And the man himself admitted that there are mixed emotions as he looked ahead to his last few days as Celtic manager.

Deila said: "It is difficult to explain. It is now a long time since I said I was going to leave, and now there are just three days left.

"It is good in one way, but in another way it is a little bit sad. I think when I get some time off, and take time to reflect, I’ll feel very proud of my two years here. I will have a lot of good memories, and I’ll feel I have a lot of experience.

“I have been honest all the time. I have been myself – that was very important to me. I understood very quickly when I came in here that this was going to be very tough. You have to be very honest with yourself, and be yourself

“I think that gets through to the fans. I admit mistakes when I have made mistakes. I’ve admitted when things haven’t been positive. I’ve also taken the responsibility when things haven’t been so good, and I think people respect that.”

Mikael Lustig believes playing international football and the annual challenge of Champions League qualification makes being a Celtic player one of the most difficult jobs in world football.

The Swede will have hardly any close season given he will be with Sweden in France for the European Championships and will have to return to his club in mid-June.

Lustig said: "Celtic is probably the worst club to play at when it comes to time off in the summer. We have qualification for the Champions League every year and if you are an international players you are going to always have games in June.

“So in a normal summer I would say you have three weeks. A lot of teams have has much as eight or nine. That is a big difference, especially here when you don’t get a break in the winter, albeit we will get one this season.

“It is, of course, tough for the body. It is not easy. The first couple of months of the season are so important for us as well and we need to be ready. In a perfect world you want to have a pre-season for four or five weeks, to build your whole body up for the season.

“But at Celtic you have to start playing games right away. That is just how it is."
