On Thursday night, the Blues drew 1-1 against Manchester United at Old Trafford in the Premier League but failed to convert numerous chances to win the game.
This season, Chelsea have struggled to score goals with £100 million signing Romelu Lukaku in a rut since joining from Inter Milan last summer.
Redknapp, the former Liverpool midfielder, thinks Chelsea’s inability to get the winner against United displayed how Thomas Tuchel’s side desperately need an in-form striker.
He said on Sky Sports: ‘I think Thomas Tuchel will think how have they not won this game. The amount of opportunities they had on the right side.
‘They felt Romelu Lukaku was going to be the missing piece to the jigsaw, the man who would get them 20, 25 goals to elevate them to the title race and it hasn’t worked out.
‘Werner’s not a natural finisher. Havertz, I love his movement. But they haven’t got that goalscorer like a Drogba or Costa who’s going to get you the 20 or 25 goals that you are going to need to win the title and that’s really where they have come up short.’
Between 2004 and 2012, Drogba bagged over 100 league goals for Chelsea as he led the club to three title triumphs. Meanwhile, Diego Costa scored 20 league goals in both seasons the west Londoners finished top between 2015 and 2017.
In comparison, Timo Werner has notched just 10 league goals since joining the Blues in 2020. Meanwhile, Lukaku has hit the back of the net only five times this season.
Speaking after the draw with United, Tuchel bemoaned his team’s lack of ruthlessness up front and claimed they were not ‘decisive enough’.
He said: ‘One team deserved to win and that was us. We didn’t take it. It was a very, very good performance but we were not decisive enough. We lacked a bit of determination in the box to win the game.
‘It sometimes happens. It’s on us to learn from it. You need to be clinical to get the reward. We have to live with a point but it’s not a fair result.’
