“So, I have seen him on that platform. For any player that is the highest level you can get to and it was not a big surprise to me that he should want to stay where he is.”
It is Lustig’s appearances in the European arena that are particularly telling with the 30-year-old defender making 50 appearances for the Hoops.
He said: “I first got to know Mikael when he was a young player coming through and I knew he wanted to play at the top level.
“He was a duel operator and that is so valuable, particularly now in the modern game where we see full-backs going further up the pitch all the time.
“But my own experiences of Mikael was that he very personable. He was always a popular member of both youth dressing rooms and the first-team dressing room because he is able to communicate very openly.
Lagerback added: “Everyone in Sweden would recognise Celtic not just because they are still one of the iconic names in football, but, of course, we had Henrik Larsson and Johan Mjallby there for a long time and they did not too badly.
“I also think that for any player if your family is settled and happy and you like the club, you believe their ambition matches your own, then it is an easy decision to stay.
“I still think that Mikael has a lot of football in him. He is coming into the peak years of his career but he is an athletic player and I still think that Celtic can see the best of him.”
