Paul Merson claims Chelsea must sign a striker in the January transfer window if they are to mount a serious title challenge.
The Blues spent over £220million on the likes of Kai Havertz and Timo Werner in the summer, but after a resounding 3-1 loss to Manchester City, they now sit ninth in the table.
And Merson has explained why he thinks Frank Lampard needs another option in attack.
He told Sky Sports: “I don’t know where Werner plays.
“I think Chelsea may have signed him to play as a striker, but that is not working, and if his best position is off the left, then Chelsea need a centre-forward.
“No disrespect to Olivier Giroud or Tammy Abraham, but you are not going to win the Premier League with those as your front two.
“Giroud and Abraham do great on their day, but they are not going to be in the top six Premier League goalscorers this season, or any season.
“How many teams have won the Premier League without having a player in the top six scorers?”
Lampard has rotated his side frequently this term and has been accused of not knowing his best team.
But Merson said one part of the team picks itself.
“Chelsea are suffering from a major dip at the moment,” he said. “Players are struggling, new signings are struggling, and four months into the season it appears that Frank Lampard does not know his best team..
“Frank has got to get a settled team. He knows his first-choice back five – Edouard Mendy, Reece James, Kurt Zouma, Thiago Silva, and Ben Chilwell – and that is solid.
“After that, it’s bingo and it’s clear he does not know his best midfield or front three.
“You would argue that N’Golo Kante and Mason Mount are next in the pecking order but that leaves Lampard needing to select four from eight internationals. Suddenly things start to mount up, and it’s hard for him to pick the right team.”
