Scotland manager Gordon Strachan has advised Celtic boss Ronny Deila to focus on "dealing with reality" and ignore comments in the media.
Deila gave a frank assessment of media criticism in a press conference on Friday, saying "jealousy" is behind the negative comments aimed at him and his players.
Celtic extended their lead at the top of the Scottish Premiership to six points after beating Aberdeen in Saturday's lunchtime kick-off at Celtic Park.
But the press in Scotland has been predicting a full-blown crisis at Parkhead, and some have even speculated that Deila will lose his job after Celtic lost 3-1 to Molde in the group stages of the Europa League last Thursday.
Strachan, who managed Celtic from 2005 to 2009, says Deila should learn to ignore the criticism that comes with managing such a big club.
"When I was Celtic manager, I used to wake up every day and wonder what was coming my way," Strachan told Sky Sports. "But that's what you have to deal with, not only at Celtic, but you feel the pressure and you feel lonely.
"But sometimes you have to take a deep breath. You have to have good counsel and the best way to deal with it, trust me, is to not listen to anything and not read anything.
"He has to just deal with reality and the reality is that they're top of the league, they're still in the Europa League.
"Everybody has to have an opinion and there are other people who want to be the manager or want to be pundits and that's fine.
"But the only opinions you've got to deal with are the ones you respect. There are ones that might annoy you but you have to ignore them."
Former Celtic striker Andy Walker, who had two spells at Parkhead, felt Deila allowed himself to be "sucked into" making comments about Rangers in Friday's press conference by "one or two idiots behind the scenes" at the club.
"I cringed when I watched it - I thought he had a wee bit more about him," he said. "He's clearly been fed these lines by one or two idiots behind the scenes and his conduct was not becoming of a Celtic manager.
"Previously he's never mentioned any other club because they've not been in the same division but all of a sudden he wants to talk about Rangers.
"I thought it was a dreadful press conference and I'm amazed that he's been sucked into dishing out the ridiculous lines he did on Friday."
