Chelsea have been linked with a move for Benfica striker Oscar Cardozo – if the Blues fail in their attempts to sign Radamel Falcao.
And, if Chelsea decide against a move for the Colombian, they will instead move for Cardozo in an effort to strengthen their attack.
Contracted at the Estadio da Luz until the summer of 2014, the man affectionately nicknamed 'the bomber' was reported to have turned down a new contract offer at the start of the month, leading to speculation that he could leave the Portuguese giants.
The 42-cap Paraguay international has been linked with a move to the Premier League in the past, with Everton boss David Moyes reported to be an admirer.
However, it’s Chelsea who have been linked with the player most frequently in the past, and a lack of options up-front would explain why Di Matteo wants to strengthen at Stamford Bridge in the New Year.
Fernando Torres and Daniel Sturridge are the only senior strikers on the books in west London at the current time, with youngster Romelu Lukaku out on loan.
With Roman Abramovich seemingly willing to open the chequebook once again in 2013, Cardozo could be the answer to the Blues' striker problem.
