Porto defender Nicolas Otamendi won't rule out a move away in January.
The Argentine is expected to sign for Chelsea at the end of the season, amid talk of agreeing a pre-contract, however, Manchester City have also expressed interest this season.
Otamendi remarked: "My mind is on Porto, though these rumours appear logical because Porto are well known worldwide. I welcome the interest in me because that means I'm doing well.
"If the opportunity arises to go, I'll think about it, but now I'm focused here."
