Chelsea rose to third in the Premier League after beating Leicester City 2-1 at Stamford Bridge on Tuesday night.
Chelsea striker Timo Werner saw two goals ruled out for offside and handball respectively.
According to Graeme Souness, Werner’s numbers for Chelsea this season have been ‘terrible’ and Thomas Tuchel must find a goalscoring solution internally or externally before next season.
Speaking to Sky Sports, Souness said: “If Chelsea had been going through a difficult time, he [Werner] would have been the target, above any other player at Chelsea, for criticism.
“His numbers are terrible for a centre forward at a big club, but he always looks like he gets chances because he is rapid, he is electric, and he would beat most people in a sprint.
“He was a goalscorer before he came to Chelsea, and it may yet happen for him, but Jorginho, your midfield player, as your top scorer with seven goals, you cannot be successful if you are relying on penalties at the highest level.
“They will have to find one [a goalscorer], whether it is Timo Werner or [Kai] Havertz or someone they bring in. They have to get an out-and-out goalscorer, and I think that is the final piece of the jigsaw for them.”
