Chelsea are prepared to make an offer for Porto striker Jackson Martinez in January if Samuel Eto'o's groin injury turns out to be more severe than first feared, according to the London Evening Standard.
The Blues are waiting to discover whether Eto'o will miss the hectic festive period after the Cameroon international was stretchered off during Tuesday night's 1-0 defeat to Basel.
Eto'o, who signed a one-year contract with the Blues in the summer, will undergo a scan later today to determine the extent of his injury.
The 32-year-old has been in good form recently - scoring three goals in his last four appearances - however, Jose Mourinho remains determined to sign another striker in January, and has identified Martinez as the perfect acquisition.
Mourinho watched the 27-year-old in action for Colombia in a recently friendly against Belgium, while it was reported that the player's agent Henrique Pompeo met Marina Granovskia, a Chelsea executive board member and senior advisor to owner Roman Abramovich, earlier this week.
Chelsea's hopes of signing Martinez, who has a €40m release clause, were also boosted recently when news emerged that he had refused to sign a contract extension with his current club.
