Former Scotland international striker Paul Dickov has told Sky Sports that pressure is natural at Celtic after questions over Ronny Deila's future.
The Bhoys have endured a tough time of late, having encountered a number of bumps in the road this season, piling the pressure on Deila.
Firstly, Celtic were dumped out of the Champions League by Malmo back in August, before they also crashed out of the Europa League, failing in a group containing Ajax, Fenerbahce and Molde.
Factor in that Deila's men were just knocked out of the Scottish League Cup by Ross County, and you begin to see why Celtic fans are growing frustrated with the Norwegian's reign, especially considering that they are unconvincingly defending their Scottish Premiership title.
Aberdeen sit joint-top of the Premiership table, and whilst Celtic do have a game in hand, Derek McInnes' Dons have real hope that they can spring a surprise by winning the title this season.
It's all played into mounting pressure on Deila's position, and boyhood Celtic fan Paul Dickov - most recently manager of English League One club Doncaster Rovers - has told Sky Sports that pressure is part of being at Celtic, given the expectation on both them and Rangers.
Dickov also stated that Celtic can't afford to miss out on the Champions League qualification, which comes with finishing top of the table, but also talked up the Bhoys' chances of winning a domestic double this season.
"I think that, first and foremost, they're sitting top of the league, and they're still in with a shout of the double, with the Scottish Cup as well," said Dickov. "Rangers and Celtic are two massive, massive clubs, and I don't think people realise the size of it."
"Celtic, without Rangers being in the same division at the minute, are expected to run away with the league up there, so the fact that Aberdeen are level on points with them is going to put them under massive about of pressure. That qualification for the Champions League going into next season is something that Celtic can't do without," he added.
