Manchester United legend Gary Neville feels Jose Mourinho needs to buy a new striker to keep Chelsea in the title race.
Chelsea drew 0-0 at Arsenal last night.
Neville told Sky Sports: "Jose Mourinho has said he's not going into the transfer market in January but I can't believe that with Chelsea's history. At the moment the difference between them and City is City can play Sergio Aguero, Alvaro Negredo and Edin Dzeko, who have real power up front and score goals. Chelsea don't have that firepower."
