Petit told Genting Casino: "I don’t think Chelsea need Gyokeres or Osimhen. With Chelsea, there are so many players who are not playing to their level and can do so much more. I think Nicolas Jackson is one of them.
"He’s got lots of potential and has shown it in glimpses but needs to do more. I think Caicedo needs to too and so does the Argentine midfielder, Enzo (Fernandez). There are many players who don’t play the way they should, there’s no confidence, they’re lost on the pitch - and it’s the same with Jackson. He’s struggling as the team is struggling.
"He’s not the type to dribble past four or five defenders and score, he’s not like that, but when Chelsea improve as a team, he will improve. That’s why I don't think Chelsea need to sign a striker - they need to stop spending so much."
