Former Chelsea defender William Gallas says they shouldn't move for Napoli striker Victor Osimhen.

Instead, Gallas insists they need to back Nicolas Jackson.

He told Lord Ping: "Victor Osimhen joining Chelsea would harm the confidence of players like Nicolas Jackson. You have to be careful and really think about bringing in a new striker. As I said before, I think Chelsea should finish the season with Jackson and see how many goals he gets.

"We also need to see how he improves. He has the quality to do so. Chelsea need to let Jackson get to work. Scoring goals will always boost the confidence of a striker, and Jackson's hat-trick against Tottenham will definitely boost him, and we'll see that confidence carry over into his next games.

"Chelsea need a striker who'll score at least 20 goals a season. I don't know if Jackson will do that, but at least he's scoring. I hope more goals come for him. I think Chelsea should stick with the squad they have. They've bought so many players, and the squad needs to get to know each other.

"It's looking like Chelsea are slowly starting to improve. I said a few months ago that the Chelsea squad isn't ready to fight for the title or qualify for the Champions League. They will, however, improve from last season. I'm sure that they'll be very strong next season and the one after."
