Former Celtic assistant coach Alan Thompson has claimed that new manager Ronny Deila could find life difficult at the club.
The 38-year-old joined the Scottish Premiership champions last week after guiding Stromsgodset to the title in his native Norway.
Thompson believes that Deila may find it difficult to adapt to the "big demands" of being Celtic manager when the new season kicks off.
"It will be difficult for him. He might need a period to settle in just to find out what it's about, because it is a huge club with big demands," he told Sky Sports News.
"You can't lose two games in a row. One game is bad enough, but if you lose two the pressure comes right on top. You find that out quickly and you have to deal with it."
Deila spent six years managing Stromsgodset before leaving for Celtic.
