Jamie Redknapp believes that the Blues should sign a new left wing-back
He also thinks they should look for a new striker in the January transfer window.
Chelsea have now secured their status as the favourites to win the Premier League title this season after their great run under new boss Antonio Conte this season.
The West London club will be on top of the Premier League table over Christmas as Conte looks to grab his first title in the Premier League.
The January transfer window is getting closer and the speculation about which players the top clubs could move to sign in the new year is beginning to gather pace.
And now Redknapp has given his assessment of what Chelsea need from the January window as Conte looks to bolster his squad and boost their title challenge.
Speaking to The Daily Mail, Redknapp said: “I’m sure Chelsea would love to find the next Ashley Cole to play in their system as a left wing back, although they are difficult to find. Marcos Alonso has done ever so well but it is an area where Chelsea can improve.
“I would also look for cover up front. Unlike Costa, Michy Batshuayi doesn’t look the most intelligent of forwards. When Costa is on form he is unplayable — he holds the ball up, scores goals and is a nasty piece of work.
“If Costa gets injured for the rest of the season, you would struggle to see how they would win the League given their back-up options.”
