Chelsea boss Graham Potter has been warned the backing from Chelsea owners Todd Boehly and Behdad Eghbali will stop if he doesn’t get results.
Chelsea have won just once in the last 11 games and are 10th in the Premier League.
Asked if Potter could be sacked, Hasselbaink told Sky Sports: “That is a really difficult question. I don’t know.
“When you’re at a big club like Chelsea and you lose two games in a row, that is already considered a crisis. Now these owners have come in, they want to go in a different direction, they want to do this project.
“They’ve bought Potter in, he’s their man so they will give him as much time as possible. But you also have to expect something back from Potter.
“And if he doesn’t [do that] then eventually that [backing] will stop. When that is I don’t know but Potter is under pressure and that’s what happens at big clubs.”
