Brendan Rodgers has done well to keep a lid on his feelings around Celtic 's lack of spending in the transfer market this summer. But the same cannot be said for Hoops fans, who aimed chants of 'sack the board' at Parkhead chiefs in Wednesday night's 0-0 home draw with Kairat Almaty that has left Rodgers ' team with some work to do if they want to reach the Champions League proper. And that ill-feeling has spilled over onto the Hotline, with owner Dermot Desmond and CEO Michael Nicholson coming under more scrutiny for their alleged lack of ambition. Paul McCormack, Coatbridge , wrote: "Rich in pound notes but bankrupt in ambition. What an awful job the decision makers have made in this transfer window yet again. They deserve every bit of the roasting they will get from fans who deserve so much better than these bed wetters in suits deliver annually." In a similar vein, Billy Barry, Dundee , added: "Now this is not a knee-jerk reaction from me, just to be clear on that, but what the hell is going on at Celtic? Ok, I understand that the board have got to be prudent financially, but that display against Kairat Almaty was, let's be honest, it was shocking! "A lot of Celtic fans were laughing at Rangers for only having one shot on target against Club Brugge, did Celtic do any better? Where is the money from last season's Champions League campaign, the £18million for Kuhn, the reported £8million for Kyogo, and going back even further, the £25million for Matt O'Reilly, etc, etc, etc? "Nine players have come in during the close season, with the highest paid for a player being £1.5 million for Nygren. Unless the Celtic board release the funds Brendan Rodgers desperately needs for genuine quality players, Celtic will struggle in the Champions League, or god forbid, the Europa League." Kenneth Wilson also called to say: "A woeful clueless performance from Celtic hardly creating a chance all night and quite easily could’ve lost the game. A tough task lies await in the second leg and how the board can’t see that the squad needs serious investment is beyond me. They should hang their heads in shame because there is every chance it will cost them a place in the Champions League." However, other Hotline callers insist boss Rodgers also has to share some of the blame for persisting with last summer's £9million signing Adam Idah. Gus Murphy, Bellshill , said: "Brendan Rodgers has been excellent since he returned to Celtic for a second stint as manager. However it's the old story of trying to prove you made a good signing when you have not Adam Idah doesn't and never will have a strikers' natural instinct for goal .He always seems to be a yard early or a yard late and that will not improve with time. When you move Maeda out wide to accommodate Idah, it's a big mistake that has a ripple effect on the whole team. "And after the pre match team talks, the players are starting the game thinking they have 10 men and a a non-striker on the park. Not good. Brendan, you need to be the bigger man and admit Idah was a mistake as he is not a natural striker and never will be and move on. Hopefully he will then will regain the full respect and support of the Celtic fans." David Bryce , commented: "Yes the Celtic board are suffocating our great club and are an absolute disgrace. However, Rodgers has to cop a lot of flak also regarding the horrid performance against Kairat. His tactics are absolutely awful and the style is horrendous. The sooner he leaves the better, he has made Celtic utterly terrible to watch. Spare me the elite manager nonsense, he should have been sacked after the Scottish Cup final." Things aren't too rosy on the other side of Glasgow at the moment, with Russell Martin failing to win over Rangers fans. The Light Blues hopes of progressing to the Champions League big time have been left hanging by a thread following their 3-1 first leg play-off defeat to Club Brugge at Ibrox but Robert Livingstone, Palm Beach , is convinced that Andrew Cavenagh and 49ers Enterprises will give him the whole season to transform the club's fortunes. He wrote: "Realistically, whatever happens over the next three games - even if the results are not good - it's unlikely Martin will be sacked. American owners don't work that way by paying contracts out after a few weeks when there are three years are still remaining. "They could leave him in place untill end of season then pull trigger if things don't improve. What these owners don't understand and probably never will is that in Glasgow, Old Firm managers live and die by results. It doesn't happen to the same extent in American sport where massive contract payments are the norm, such as in the NFL, NBL and MLB where they are usually seen out." Melvin Gess reckons Martin's time could be up if they don't get one over Celtic in the first Old Firm derby clash of the season on August 31. He added: "Hello Sports Hotline, please forgive the lack of brevity but I have waited a very long time before contacting you. "I have supported Rangers all my life. I proudly had their name tattooed on my arm over 50 years ago and have had plenty of good and not so good memories. The Souness and Smith years were heaven sent but we now it feels we are descending into the seventh circle of hell. "I believe every new manager deserves our full support and be given enough time to implement their strategies and philosophy. However, as much as I want Russell Martin to succeed, I am starting to think his tactics belong in the world of fantasy football. Decent sides will now how to exploit our tactical deficiencies. "In his interviews his favourite line is he wants to see his players to run. Maybe after the Celtic game he may have to run back down south!"
