Chelsea manager Jose Mourinho has revealed that striker Fernando Torres faces four weeks on the sidelines with a lateral ligament injury.

Torres suffered the knee problem shortly after being introduced as a substitute against Manchester United last weekend, but Mourinho has insisted that the Spaniard won't require surgery.

Asked how long Torres would be absent, the 50-year-old told reporters: "One month, three weeks. Something like that.

"It's not a surgery situation but it's not a little strain. It's a lateral ligament injury."

Torres has scored eight times in 23 appearances for the Blues during the current campaign.
