Ferrari needs to win in Barcelona to keep its championship hopes alive.
That is the view of former F1 driver Ralf Schumacher, who said the pressure on the Maranello team in Spain is "enormous".
"Their potential is there, but wrong decisions, a technical problem and some driving errors has meant they have not fully exploited it," he told Sky Deutschland.
"Actually, almost nothing but a victory in Barcelona will keep the championship open for them," Schumacher said.
And he says the pressure on Sebastian Vettel is even higher.
"First, you have the mistakes he has made and his lack of results. And then his teammate Charles Leclerc is making his life even more difficult," said the former Williams driver.
"Leclerc currently has a tailwind as he gets more confidence from race to race. Vettel needs to push hard to have the edge in Barcelona," added Schumacher.
He said Ferrari not only has to worry about Mercedes, but also Red Bull.
"Red Bull has a large update for the European season and if it brings what they expect, Max Verstappen could be a surprise," said Ralf.
"Overall, I think Ferrari has the best package, but Mercedes is the more complete team with perhaps more complete drivers. And Ferrari cannot afford any more mistakes."
