Ralf Schumacher is not convinced that Ferrari will be able to resolve their issues in time for the Canadian Grand Prix.
The Scuderia suffered a nightmare race at the Azerbaijan Grand Prix, with both cars having retired with mechanical issues by Lap 21 of the 51-lap event.
In terms of what might have led to the problems, Schumacher thinks there are a couple of potential causes.
"Ferrari suffered a debacle with the retirement of Charles Leclerc and Carlos Sainz," Schumacher wrote in his column for Sky Sports.
"One cause could be a poor supply of materials. But it could also be that the engines are overloaded and have a shorter life span than expected."
Schumacher: Ferrari in a "bad way"
Schumacher believes that the situation at Ferrari is "dramatic", and adds that team boss Mattia Binotto may have a difficult task on his hands in finding a way forward.
"Ferrari are in a bad way, it has to be said," the former F1 driver commented.
"The situation is dramatic and Mattia Binotto has a difficult job. After the strong start, it was first the declining consistency of the drivers, then technical things. And this at a time when, in terms of potential, you could win the World Championship."
With just days to go until the next round of the F1 season takes place in Montreal, Schumacher thinks that the Italian outfit might struggle to put fixes in place before then.
"They have to find a solution quickly, but I don't think the Scuderia can get their problems under control before the Canadian GP," he added.

The championship battle can still change, says Schumacher
Ferrari have fallen 80 points behind Red Bull in the Constructors' Championship in light of their difficulties in Azerbaijan, while Leclerc has slipped to third in the Drivers' standings, with Max Verstappen extending his lead at the top further.
However, Schumacher acknowledges that things can still change in the title battle.
"I think we will see a lot more this season," he explained.
"Red Bull had bad luck at the beginning of the season, nobody is immune to a retirement. The cars are more fragile because the stresses are so high."
