There was mutiny in the air last night when Celtic picked their lines and worked into a scoreless draw against Kairat Almaty in the first stage of their Champions League qualification in Parkhead.
It was a huge missed opportunity in front of Brendan Rodgers, because they did not have a benefit before the return bone in Kazakhstan in Kazakhstan next week.
Furious supporters turned their anger on the board about a lack of transfer activity in the summer, with the team shortage of quality in important areas.
Here, Daily Mail Sport looks a look in some of the most important problems that come to the fore when the chickens came home to ray for the Celtic hierarchy.
Regression since Munich
When Celtic arrived in February within a few seconds after winning Bayern Munich, it felt like Club had a positive momentum in Europe. They gave a great report of themselves in the Allianz Arena, went to toe with a good European heavyweight and played well at night.
They were ready to take the Bavarian Giants all the way to extra-time in a knockout similar game from the Champions League and it was almost one of their best results ever in Europe until a last-gasp goal from Alphonso Davies broke their hearts and she switched off.
Yet it still felt even the start of something.
How can things have gone so badly in the room of six months? Celtic not only did not build on those performance against Bayern, they have also deteriorated. They have declined.
Brendan Rodgers did his best to be diplomatic about it last night in his media conference after the game, but it was still clear that he is not happy.
There was mutiny in the stands, with songs of 'Sack the Board' that echoed around the stadium. Michael Nicholson and Peter Lawwell gave up the big of fans and stood in the main position full of time immobile.
By not investing in a new striker and a few new broad players, the Celtic hierarchy Rodgers sent to this Champions League qualifying match under the other and poorly equipped.
Kyogo Furuhashi left the club in January and Celtic still did not replace it. Nicolas Kuhn, scorer that night in Munich, worked his ticket for months before he left this summer.
Celtic's efforts to bring new talent to the club have been icy. It has been a gamble of £ 40 million that is now a serious danger to work offset.
Johnston Injury A huge concern
One of Celtic's most consistent artists since he arrived a few years ago, Alistair Johnston is excellent on right back. But he went under the first half last night and grabbed his hamstring before he was stretched.
It was a regrettable view and Rodgers will sweat on the fitness of the Canadian international. An update is expected in the coming days, but it seems almost certain that Johnston will get a period on the sidelines. Exactly how long we don't know, but it can very well reduce Celtic in the transfer market for more coverage on right back.
If it is confirmed that Johnston will be released for a longer period, there is no way that Celtic can continue with Anthony Ralston as their only option on the right side of the defense.
Adam Idah's misery continues
To say that Adam Idah had a fairly tame and not -inspiring start of the new season, it would be to say the least.
After a 2-0 win at Aberdeen a few weeks ago, Brendan Rodgers quickly defended the striker despite another ineffective performance and he insisted that the Irishman needed more competition in advance to rediscover his spark. But that was just Piffle. The reality is that Idah did not succeed in understanding the opportunity he had when Kyogo Furuhashi left the club in January.
There was no hiding place last night, with rodgers who protested against the touchline at a certain point halfway through the first half and gestures about a lack of movement. Without clear improvement, Idah was addicted during the break.
Rodgers later said that he 'could not wait' for Idah, which is why he made the change. He was replaced by Yang Hyun-Jun and the winger immediately made more impact, in which Daizzen Maeda moved through the center like the central striker.
Auston Trusty's future?
Towards the end of last season, Auston Trusty lost his place in Celtic's first choice that XI started. So much was clear when he was giving birth to the Scottish Cup final against Aberdeen in Hampden, with Liam Scales that start in central defense next to Cameron Carter vickers.
At the start of the new campaign, Trusty is again on the periphery. He has so far only started one of the four games of Celtic, against Falkirk in the Premier Sports Cup, with scales and carter vickers the preferred partner again last night.
Jahmai Simpson-Pusey is on loan from Manchester City and clearly gets a considerable amount of playing time, otherwise City would not have agreed to the move.
Trusty has to look at scales and wonder how the hell he cannot get to the team for him. Scales struggled poorly against Almaty's powerful striker Edmilson last night.
Admittedly, Trusty made some mistakes last season, but the fact remains that he is a better player than scales. He arrived in Celtic for £ 6 million last season and is an international at America. With a World Cup to look forward to the home floor next summer, it will spend a season on Celtic's couch just not cut it. He has to play football. Otherwise he could well ask to leave the club before the end of the transfer window.
Dastan Satpayev … the next star on Stamford Bridge?
Earlier this year it was announced that Almaty Teenager Dastan Satpayev will join Chelsea for a reimbursement of approximately £ 3.3 million. Satpayev is only 17 years old and will join the blues when he turns 18 next summer.
He is seen as the great hope of Kazakh -football and some people can sniff that well. It is the kind of compliment that can be seen well in the same light as the best dressed man in Albania are called.
But there is undoubtedly a talent in Satpayev. He was paramount in many of their best moments in the attack in Celtic Park. He is a very agile player with fast feet, good pace and a capacity to play over the front line.
Breaking into the arrangement of the first Chelsea team is not an easy task given the cast of thousands of available for Enzo Maresca. At his disposal, the Italian has the most extensive assembled team in Europe. But if Satpayev can get a full season of Champions League development under his belt before he goes to Stamford Bridge, it would do him the world of good.
