Former Chelsea player Emmanuel Petit has advised the club not to sign a striker this summer.
Petit believes Nico Jackson has shown what he is capable of over the last few months and should not be put under pressure.
"Chelsea do not need [Victor] Osimhen or [Alexander] Isak," said the World Cup-winning midfielder.
"We all know about the No.9 curse at Chelsea and in the last couple of months, we’ve seen what [Nicolas] Jackson can do.
"There’s no need to put more pressure on him by signing someone like Isak on his back.
"You need competition in every position, but when you have someone like Jackson starting to emerge, don’t put pressure on him and let him explode.
"For me, if I’m Chelsea, I'm not buying Isak as Jackson is already beginning to flourish."
