Former Anzhi Makhachkala assistant coach Roberto Carlos claims that the club will collapse within two years if drastic action is not taken.
The Dagestan club made headlines for their ambitious spending but a change of policy this summer prompted the sale of a number of their star players, including Samuel Eto'o to Chelsea.
And the ex-Brazil international now believes that the absence of himself and coach Guus Hiddink will leave the club a laughing stock in Europe this year.
"If Hiddink and I are gone, the entire command structure will collapse," Roberto Carlos told Sport Express, "but I didn't think it would happen so soon.
"If I had stayed in at Anzhi, this would not happen. The team simply does not have enough experience.
"Makhachkala will look ridiculous in the Europa League, unless they hire a good coach and a good sports director. At this pace the club will collapse in the next two years."
The 40-year-old left Anzhi in the summer to take the reins at Turkish side Sivasspor.
