Former Celtic defender Ramon Vega has told The Herald that Ronny Deila should be under pressure - and should face the sack if he fails in the Europa League.
Celtic lost 2-1 to Aberdeen on Saturday, which has given the Dons - widely believed to be Celtic's top competition for the Scottish Premiership title this term - hope that they can spring a surprise and win the league.
The defeat came at the worst possible time for Deila, who has been dealt blow after blow over the last month. Firstly, he saw his side crash out of the Champions League in the play-offs after a two-legged defeat to Swedish champions Malmo, which was the second straight year that Deila has failed to take Celtic to the group stages of the Champions League.
Then, star defender Virgil van Dijk left the club to join Premier League outfit Southampton, leaving Celtic with a huge hole to fill in their back line.
Many Bhoys fans are now beginning to question Deila, with the Norwegian now coming under increasing pressure - and Ramon Vega agrees that Deila should be far from safe in his role as manager.
Speaking to The Herald, ex-Bhoys defender Vega says that Celtic may have to consider looking for another manager at some point this season if Deila's struggles continues, and suggested that if he fails to take Celtic out of their Europa League group, Celtic will have a big problem on their hands.
"The pressure is always on the manager," said Vega. "Unfortunately for the manager, you are the only one the pressure is on. At Celtic even more. Doing well in Europe is pretty much essential for Celtic. It is the financial impact it has at the football club. It is very important the manager gets it right. Otherwise Celtic Football Club or the CEO has to look to something else."
"You have a problem if he doesn’t qualify for the knockout stages. Are you going to stick with this manager until the end of the season if he doesn’t go through in the Europa League? Can they be confident he will qualify for the Champions League next season? That is the risk in football. That is the risk a board member or a CEO has to take. But they need to make the decision," he added.
Celtic's Europa League group contains Ajax, Fenerbahce and Molde, forming an incredibly difficult group for Deila and the Bhoys - but failure to claim one of the two top spots in the group could really pile the pressure on the 39-year-old manager.
