Juventus have entered negotiations for Porto’s Jackson Martinez, according to Italian site Calciomercato.

While initial reports are sketchy and only seem to appear on Calciomercato.it, the website are suggesting Juventus have already entered into negotiations with Porto for their Colombian striker.

The Bianconeri are currently working on a loan deal for Portuguese defender Rolando and may have possibly turned their attentions to Martinez as well, during discussions with Porto.

According to Calciomercato, negotiations will not be straight forward and are unlikely to be resolved in the winter transfer window. Porto value the striker at around the €35m mark, a figure Juventus are not prepared to meet as they prefer to include players in the deal.

Juventus are supposedly beginning their search for a striker following Carlos Tevez’ admission that he would not be renewing with the Bianconeri beyond the end of his existing contract which runs until 2016.
